Yeah, I remember back when I was a cringy teenager and bought into all the propaganda about why darkmode was better for eyes and whatnot, so much stuff..
So I spent 15 years or so with darkmode, untile one day, i read somewhere that the evidence of darkmode being better was not just lacking, but that people read dark letters on a bright background faster and more accurately than the other way around.. Now this is the Internet, with a capital I so I won't back up that claim with any references, and it's not important whether anyone believes that or not, fact is, that day, I thought "hm" and I switched my editor back to light mode and thought "hm, this is fine too" and I kept it long enough that I discovered that I prefer it.. Now, my xterm, I do want white on black, but that's just something about how that bitmap font looks to my eyes, that makes me want it that way.
But honestly, I don't get what the big deal is with either preference, it's not a big deal really.. black or white.. it's fine!
I use light mode during the day and dark mode from dusk till dawn. I do this because I find it more comfortable, not because I'm told by someone or a study that it's better.
that's fair, the study didn't convince me it was better, it just prompted me to switch back to white, because, actually, I don't know, and then I found that _if_ it made any difference, it was probably positive, but, even though I sit at the screen from dusk till dawn, I find no difference in how pleasant light or dark mode it, it just makes so little difference to me that I don't care :)
But honestly, I don't get what the big deal is with either preference, it's not a big deal really.. black or white.. it's fine!
