On practical how to:

1. Keep two water reservoirs for cleaning your brushes. One for warm colors and one for cool. (This prevents muddiness in your palette).

2. Knowing when to let the layers on your paper dry before further progress is vital.

3. Carry pigment from the bricks to your palette, don't mix pigments in the bricks.

On technique:

1. Experiment adding water to a pigment on your palette (More water == thinner with less Saturation and vice-versa).

2. Experiment with how wet pigments interact with other wet pigments on the paper. (More water == better flow).

3. Experiment with the paper tilt direction (water flows under the force of gravity and this can be used to create a desired affect).

4. Know how to layer (i.e., 1st layer low saturation, broad areas with high water/flow, final layer is fine detail lines with low flow/higher saturation).

5. You must understand the color wheel and how pigments may mix.

I have beef with this guidance:

> let your palette and paint bricks get dirty

Keep your bricks clean: Let your palette get dirty (if you so choose).


> Keep two water reservoirs for cleaning your brushes. One for warm colors and one for cool. (This prevents muddiness in your palette).

I used to do a cup of designated dirty water and a cup of clean water but I can't think on that level when I'm painting. I'm close enough to a sink that I just change it out as needed. Any cup near me when I'm painting is going to get all manner of brushes dunked in it. Yes, I've dunked a paint-loaded brush in my coffee before.

> Knowing when to let the layers on your paper dry before further progress is vital.

Only slightly less vital: knowing when not to let the layers on your paper dry before progressing. But yeah, that one first.


This all seems like sound(er) advice.

On color : I recently realised (or read somewhere) about the simplest color wheel- if you divide a circle into 6 segments and paint the primaries : {R, Y, B} in non-neighbouring segments, then the ones in between are the secondaries: {R+Y=O, R+B=P, Y+B=G}. Then if you combine primaries and the 'opposite' secondary, you get brown/grey like colors.

Also, I get quite good combinations (palettes) by using a mixture of the same colors, like a red and a green and then a mix of the two to make a grey.

I've thinking about using https://github.com/scrtwpns/pigment-mixing to go from a desired RGB output to the {RGB1, RGB2, percentage) inputs somehow. Would have to be quite rough estimate though, as mixing real paints in exact proportions seems hard.


If you want to get things right, I suggest looking at Peter Donahue's Colordisk. He has several great explainers up on Tiktok (sic.), and he has several variants of his Colordisk freely available (his URL shortening, not mine):

https://bit.ly/3gczeBz


I never realised the colour wheel can be navigated using the ab coordinates from Lab space! That makes so much sense.

I've had trouble remembering what the ab coordinates mean, but if I just imagine them on the colour wheel it's obvious that a goes from torquoise-ish to its complement magenta and b goes orthogonal to that, from purple-blue to its complement yellow.

Thanks for linking!


Thanks, that looks very helpful. I have a 'Pocket color wheel' that works ok, but I see that link has a more sophisticated division of color space. Nice!


Is it Red/Yellow/Blue? I believe we were lied to in elementary school — Magenta/Yellow/Cyan are the real pigment primaries.

I always wondered why when we mixed blue and yellow it made for a really muddy green.


RGB are the primary colors used in additive color mixing, CMYK are used as the primary colors for subtractive color mixing which is used in offset printing and similar processes.


In reality, artists often use different base colors anyway. One way to do it is to have 2 versions of the base colors, one warm, one cold. The reason is that for example a greenish blue like Cyan would make it harder to mix vivid violets (by adding a red on the other direction of the color wheel). So you use a greenish blue (Cyan) and a redish blue (e.g. Aquamarine), a blueish red (e.g. Magenta) and a yellow-ish red, and so on.


> primaries and the 'opposite' secondary

The fancy color theory word for this relationship is "complementary".

> a red and a green and then a mix of the two to make a grey.

If you need a black (though you seldom do) it's a good trick to mix one from the colors you're already using.


My experience in physical media makes me want to add

1a: Keep your water reservoirs well away from your drinking water. This prevents drinking paint.

:)


Cats will drink it - regardless


If by drink you mean 'knock over then lap at the mess', then yes.


Somewhat like your #4: Paint light areas first, dark areas last?

I'm not a watercolor painter but have heard this before — since watercolors are transparent, not opaque like gouache/oil/acrylic.


Don't ruin your acid-free paper by using tap water, use bottled water for everything, including cleaning your brushes (valid for every water-based technic like acrylic, tempera, guache...).


By "bottled water" do you happen to mean "distilled water"?


pellegrino


No, just mineral water.


Isn't most bottled water essentially the same as tap water? What is the problem with tap water that needs to be avoided?


This really depends on where you live. Consider yourself lucky if it is the same.


Bottled water typically doesn't have chlorine, through I'm not sure what that does to water-coloring.


or floride -- oh crap, actually, i'm wrong. lots of bottled water has floride.

https://fluoridealert.org/content/bottled-water/


what does fluoride do to watercolors?


It turns it into Communist propaganda, Mandrake.


And impurifies our precious bodily fluids.


Do you have any advice on how to deal with paper warping?

The paper getting sobby and uneven often quickly brings a painting session to an end :)

And yet in tutorial videos I often see people paint a whole background section in one go (even as much as half the page) without any issues. Do they glue the sheet down to a board?


1) look up videos of "watercolor paper stretching" on youtube, and clamp the paper down if you can (I'll tape all way around a sheet to make a nice border anyways).

2) alternately use watercolor paper blocks (which have adhesive on all sides of the sheet, which minimizes curling)

3) get heavier paper (thicker), use less water, and don't let water pool anywhere.


I use flat magnets in pairs - like neodymium ones, but disc shaped.

Like these (although I don't know the exact brand of mine):

https://www.eclipsemagnetics.com/products/magnetic-tools-and...


Oh very clever! Less of a mess than tape. Thanks for the idea :)


Get thicker paper


It's kind of funny to read that. It's a sort of rationalist's advice in that it seeks to match a consensus bell curve. Much of it is good advice but there are lots of exceptions that ought to be tweaked through subjective practice.

BTW here's a favorite little project.

Go to your local craft store and buy some tube watercolors in the hues you like.

Get an altoids tin and a lego flat base that fits inside of it. Flip the base upside down and put it inside.

Get some lego bricks, turn them upside down, use needlenose pliers to extract the circle part so there's room to squeeze in your paints. Use a twist-pull motion and it's easy to get those plastic bits out.

Squeeze in the paint, let each color form a mound at the top of the brick (this'll shrink), and put them outside to dry.

As you get new watercolor hues you like, add/subtract to the palette lego set.

With any extra room in the tin, fold up some paper towel or cut a sponge to fit.

(BTW if you plan to sketch outside, be careful about doing so in front of cars, or if you're sketching cars, use a large pad and not a small one. I've had a person go off on me for "writing tickets" in free parking zones when I was sketching a lovely coupe...)


Reminds me of a similar experience when first shooting street photos with a deceptively compact zoom lens. After capturing a close-up of a sign someone well out of frame berated me for allegedly taking photos of him. I suspect if I’d used a larger lens he wouldn’t have been confused.


Ah, that must have sucked. Photography can be _really_ bad for that kind of thing. Especially IMO since a lot of people think regular cameras are obsolete unless you are on Official Business. Just use your phone, etc.

You reminded me of one time when I was out walking with the idea of capturing some aircraft, so I had a superzoom with me. While walking into the hills I saw a house that was for sale, and I happened to be looking for a house, so I snapped a photo.

Some weeks later I greeted an acquaintance-neighbor on the street and they looked kind of conflicted while we spoke. After I crossed the street, post-greeting, they called out, "HEY, WHY ARE YOU TAKING PICTURES OF PEOPLES' HOUSES?" and I had no idea what to make of that...only to realize hours later that they lived across the street from the house that was for sale. Geez. I'll bet they absolutely hated the fact that the mysterious house photog greeted them like a normal person would!


In some Southern European countries (Greece or Turkey IIRC), photographers with long lenses will be arrested if they are caught near an airport that hosts any sort of military aircraft.


Yes, IME if you walk around with a footlong telephoto lens they'll just get upset and/or confront you for slightly different reasons, though.


> It's a sort of rationalist's advice in that it seeks to match a consensus bell curve. Much of it is good advice but there are lots of exceptions that ought to be tweaked through subjective practice.

My wife is an artist, and by the law of association, I have I many artist friends. I would say that starting out, the good advice that matches the bell curve is great for getting started. Learn the basics before you break the rules. That way you know you are breaking the rules and why.


Hard disagree on cheap pigment. Windsor and Newton Cotman Colors are "student quality", so they're more affordable because they have less pigment. As a result, your paint seems thin and light.

Use Daniel Smith tubes, or M. Graham tubes. Twelve small tubes might cost you ~$100-120, but they'll last for about a year if you paint every week. These brands give you *very* rich colors.

Learning to draw, paint, and mix colors is time consuming. It's best to get started with medium quality brushes and paper, and then move on to expensive brushes and paper after a year or two, by then you should be able to appreciate the relative difference between serviceable and high quality materials.

Kudos for getting this page together. I've only ever had mediocre results with Cotman watercolours which can give muddy results and I absolutely disagree with buying cheap paper. When I started buying the most expensive watercolour paper I could afford (300 gsm) my watercolour practice got much better. Obviously that is just my experience and people have to work out what works for them. I'm on Instagram @chloegilbertartist and if you scroll you will get to my watercolours.


Agreed. Good paper that can handle a extra water makes all the difference. It doesn't need to be super expensive... just not the cheap stuff.


I get Strathmore, the largest size I find then I cut it out smaller with the help of a cutting press (free for use at Fedex/Kinkos or Office Depot). It helps save a lot of money that way.


Those choices are bad: watercolor supplies need to have be of high quality to not frustrate the painter. Otherwise you'll have bad result (destroyed paper for example, oversaturated or muddy color) and will have to fight every bit. When I was studying illustration, our teacher would advise us to avoid those kind of kit and paper. I've tried the one from children: that's not a pleasant experience.

Last thing: watercolor is one of the hardest technique you can try. You need to be able to work fast, be precise and not overwork it.


Yeah, "brush quality doesn't matter" is horrid advice. My watercolor teacher required us to buy only one brush, a pricey squirrel hair. The difference between that and a cheap acrylic brush is so great they shouldn't even have the same name.


Came to say the same, though there was a lot of bad advice in the thing.

It isn't that brush quality always matters: I'm not as concerned with brush quality when I use acrylics. Watercolor, however, it matters. Upgrading my brushes to Kolinsky sable brushes seriously improved my watercolors. It doesn't need to be sable: Folks have good success with others too. They do need some quality, though.


I came to say the same thing. I paint in oil but I would imagine with watercolors being so delicate and sensitive materials would make a big difference.


I have a few Kolinsky sables- made of a Russian weasel's tail. Really nice brush.


Cotman are okay, but brushes are so important, and for watercolor they last forever.

My recommendations...

Student Paints: Cotman as mentioned, or Van Gogh

Pro Paints: Daniel Smith Essential set (6 tubes)

Brush: Size 10 Escoda Perla. That's it!

Paper: Hahnemühle Watercolour Sketch Book


I don't read this is a "watercoloring guide for experts" but more as a "so you've seen those children's watercoloring books at walmart and you want to take things a step further".


It is still bad advice. I've spent some years giving advice to beginners, and some of these are simply going to make things more difficult at first.


This article contains what I would call unorthodox advice.

Here are my own recommendations regarding tools (I won't give advice how to paint, unlike the OP): you will need 5 tools only:

- colours: get a Lukas (preferred) or Schmincke set, a box with 12 half-bricks of colours will last for a long time and provide plenty of choice, 50-70 €;

- 2-3 brushes: only natural horse hair, one medium, one thinker and if you can afford three a thinner one, 30 €;

- paper: thick watercolour paper A5 to A3, well-glued, 15-25 €;

- 1 soft thin pencil to pre-sketch, e.g. Faber-Castell, 2-3 €;

- a glass (e.g. ordinary drinking glass or former pickles container) 200-400 ml, 0 €;

So 120-150 € give you a fantastic equipment, which may not be cheap but the cost of a good table-tennis bat is in the same range; the paper will be a costly repeat purchase if you stick to it, but the other tools can last for a long time (depending on how prolific a painter you are, of course).

(In my opinion, the quality of the brush and the quality of the paper matter the most.)

Edit: This selection has a strong German bias based on where I grew up but also because Germany, Japan and a few other countries also have a long-standing reputation for high quality stationary.


Most who will try this will probably drop it after 2-3 paintings. So it's wasteful to start with the high quality stuff.


No, because otherwise you will be frustrated with the difficulties arising from the bad materials. Watercolor is hard, don’t make it even harder on yourself.

Beside it’s cheap compare to most hobby, even with quality stuffs.


Too opinionated advice on an even worse medium. Please do yourself and the rest of us a favor and open a blog. Reading an article about watercolor basics which is basically a wall of text without a single picture is a pita.

Also some of the advice is just plain wrong. Paper should be the number one thing you shouldn't skimp on and yet you recommend buying cheap/on sale.


It isn't horrible advice: Good paper is expensive and if you can buy it on sale, you most definitely should.

And while good paper will absolutely make it easier to learn, it doesn't need to be the best paper. Just understand that the cheapest paper is usually worthless and that the next step up will cause a few struggles. I'd rather have cheap paper than bad brushes, though. (I learned on thin paper, some of it cheap)


Paper quality is one of the most impactful factor of your setup. Don't even try to do water heavy techniques or glazing on something that is not 100% cotton. If you do, it won't look great, will be a pain to work with, and you won't understand why it doesn't work like the tutorial you're watching. I still use a non 100% cotton paper for practice, but you have to know the limitations.

For paints, look at reputable brands and start with their student grade. It's often the same quality but with fewer pigments. It means that you'll have to fight with your paint more to get darker values. Watercolor is a relatively inexpensive medium, you can graduate to better paints later. You don't need more than 12 colors at first.

To start, find a style you like and search content on youtube. There is a ton of great artists sharing their knowledge out there with a wide variety of processes.

My most important advice would be :

- Learn the color wheel and how to mix paint (rarely use paint straight off the tube, it's often too saturated)

- Value is by far the most important thing to nail. It's the bones of your painting.

- Watercolor is one of the most difficult medium to master. It can be hard to grasp the technique while learning about light, edges, composition, and other painting standards. I learned my fundamentals in digital painting, which is much more forgiving, and would recommend it to anyone (you can find cheap tablets like Huion for 50$ and it works just as well as a 150$ Wacom). For digital, I can't recommend the course from Craig Mullins on Schoolism enough. He's not only one of the greatest digital painter out there, but a great teacher too.


I think the biggest missing piece is find a local art store. Local indie places are amazing, but even a chain like Dick Blick is great. Even a craft store can work, but make that your last option. The benefit is that the employees are usually artists as well and can answer questions. Its great to ask "is this $100 thing really better than this $15 dollar thing?"


Neat, I haven't water colored since I was a child, maybe I should try it again.

Now to find a tutorial on how to art. Perhaps there is a book on it, like "How to Art with Watercolor" or "Teach yourself to Watercolor in 24 hours".


It's good to read books on how to do it, of course. However, I started out a couple of years ago just making small pictures as quickly as possible over lunch.

If you don't set too high expectations, it's great to just experiment on cheap paper to see what can be done, and get a feel for it before trying to actually make a scene or paint something 'serious' that you might want to show others.

YMMV, perhaps some people get more out of it using a course or from a guide.


"Watercolor in a month of lunches"


GurneyJourney.blogspot.com is a treasure trove of great advice and information.


james gurney is a great artist and I find his youtube videos instructive, although mostly it seems like he paints with gouache over casein and no matter what you might hear, gouache is NOT similar to watercolor even if they're both water media.


He does have a course called “watercolor in the wild” though I can’t vouch for it as I only draw in charcoal.


from original post person - added some basic somewhat pertinent history - thanks for all the upvotes / stars / unsolicited criticism ;^)

> ## History

* history is cool but optional * watercolor originates from africa / the middle east * where gum arabic comes from traditionally * it was used to produce ancient artworks / maybe prehistoric * it reached europe in the middle ages * used for spooky illuminated manuscripts * gum arabic is the traditional binder in watercolor * fun fact you can eat gum arabic and they use it in desserts * it smells delicious * dont eat your watercolors * all paint is primarily pigment + binder * oil paint uses oil as its binder * acrylic uses acrylic * watercolor uses gum arabic or synthetic replacements * its special property is its water solubility * it remains semi-soluble even after drying * but it resists increasingly as it ages * thats why you use water with it * also why you can layer etc * good to know maybe


Traditionally, tempera paints use egg yolk as a binder. Don't eat your tempera either.


Some of these concepts are new to me if someone that has an art background could expand on these, maybe with a graphic example if possible.

    > zoom WAY in on subjects
    > force shapes / objects to fall off edge / zoom in
    > no un-broken edges
    > don't let yourself think about objects / people / things


> zoom WAY in on subjects

> force shapes / objects to fall off edge / zoom in

This is a composition hack. The extreme alternative is to paint an entire thing sitting smack in the middle of the page all by itself. That's probably not going to look as interesting. Mind that the author prefaced these tips with some context: "For expressive observational painting more than rigid illustration"

> don't let yourself think about objects / people / things

Paint what you see, not what you think you see. In drawing this usually manifests as the fact that you'll be more accurate if you focus on say, drawing a precise contour where a nose ought to go than focusing on drawing a nose.


Highly recommend Kuretake GANSAI TAMBI watercolors.


There are some of these pieces of advice I don't agree with, but that probably don't matter until you have some experience and know the difference.

Paints section

bricks not tubes is not a rule I'd ever follow, and many nice paints are only available as tubes. You can make bricks out of tubes as well.

More money up to $30 for what? One paint tube? A paint set?

Check pigments - what does that mean to a beginner? Nothing.

Brush section

list of rules, including a rule about no rules, is a little ridiculous.

natural vs synthetic does matter - different brushes can hold differing amount of water which affects how you paint, especially in watercolor where you don't want dry edges if you want to blend sections together. They also hold shape differently, even different natural fibers hold shape differently.

a medium round might be "all you need" without considering frustration or different techniques, but you might get a lot less frustrated having different brush shapes, and open yourself up to using different brush techniques the round won't work with.

Paper Section

Definitely don't buy paper just because its cheap.

Open it up feel the paper - for what? Until a beginner knows what they like, what area they feeling for? It's advice that doesn't help anyone do anything.

Medium heavy...relative to what? Depends on how much water you plan on using too.

paper size...depends on what you want to make. "postcard to printer paper sizes" might be ok for some things, but its small for something hanging on a wall.

trust your gut, trial and error - those are opposite recommendations. "make mistakes until you get it right" is not really advice.

I do recommend watercolor blocks, especially if they hold all edges of the watercolor paper so you have to worry less about stretching.

>old school / fun / unecessary -> this is not advice, it doesn't even mentioned what its talking about.

100% cotton paper is not "unnecessary/unnoticeable". It is definitely noticeable in how well the paper holds up to water and repeated washes, correcting mistakes, etc.

>paper weight is in lbs or gsm usually - is that advice?

>if it feels thick enough it is -> again depends on what you're intending

Other materials

Needs to recommend a hair dryer (if working at home) to speed up wash drying

The whole painting advice section is sort of...not a good way to learn any graphic discipline - graphic disciplines should be shown/demo'd graphically.


Is it me or anyone else seeing more and more articles that include lists/how to’s/procedures being shared on GitHub?


I always enjoy the water color artwork by Bill Watterson in Calvin and Hobbes. Would be fun to watch him paint.


Off-topic: this is what we get when people start using Roam/Dynalist/Workflowy for their notes?!


As others here are pointing out, there are a lot of points here that won't hold up for more experienced artists.

For example, on brushes: "a medium round (the pointy but wide-ish one) is all you need"

This depends entirely on technique and what you want to do. Trying to do consistent, smooth lines using a round brush? Good luck.


"Trying to do consistent, smooth lines using a round brush? Good luck."

It just takes practice. As long as it is the proper size for the line you are making and it holds a decent point, though, it isn't so much of an issue. Rigger brushes are long-bristled, thin, and round and used for lines, after all.


A rigger brush is specialized for lines - a "medium round (the pointy but wide-ish one)" is not, and will most definitely frustrate a beginner who is trying to do good consistent line work.

The first rule for choosing a brush should be to choose the correct one for the job. Sure, an experienced artist will have better brush control, but this guide is for beginners.


Not an artist at all, but I loved the items on gum arabic.


There's some good advice here but this one is 100% wrong:

> natural vs. synthetic hair doesn't matter


Or just get a GAN to do it.
