Is this just my device, or is there no way to use this roll-your-own SVG generator to actually roll your own? I can only pick from a tiny subset of preset colors, most of which seem super random and desaturated and not what I want. There's no FFFF00 yellow, for instance. Is there some way to enter an arbitrary RGB color that I am not seeing? If not, why on Earth write such an interesting article, advertise this custom SVG generator and then build the interface that way? :/
Does tapping on the horizontal color box to the right of the sentence “Select any color” under heading “Inside Color (Circle)” open a color picker? If not, perhaps your browser has a defective <input type=color> implementation, i.e. Firefox for Android [1796343]?
