I'd be happy to tweak the colors a bit to something that works better for you, would you like to make a concrete suggestion? We could try that out and see if there are complaints the go beyond aesthetics.

If that doesn't work, another solution would be to make colors configurable. That feature existed in the past to some extent, but I'd rather aim to keep the number of configuration options low.

I had a chat about this last year on a Discord and I did get the impression that some people are really used to the current colors and wouldn't want it to change. (Specifically my workaround has been loading puzzlink puzzles into penpa, and I had proposed changing the secondary color there and there was reasonable pushback; however, penpa does let you configure the secondary color globally so that works.)

If you want to just change it for everyone, maybe keeping the same overall shades but making them more distinct would help. On the link above, I find "Yellow" and "Lime" very similar, but "Yellow" and "Green" are very distinct (due to darkness basically). That's ffe119 and 3cb44b. Or really, just changing qsubcolor1 to 3cb44b would be sufficient.

I'd be happy with configurability too but understand that more knobs means more complexity.

Or how about we set the colors via CSS, and provide an accessible alternative stylesheet (not sure how good browser support is in general for choosing alternate stylesheets, though). I don't think it's easy for users to provide their own styles these days, is it?

I hope whatever solution is chosen works on Android Chrome :)

Another tool to look at for comparison is the player at kwontomloop.com. It does a number of things a bit differently (black for the loop, doesn't entirely fill the the grid cells), but could the shading colors used there work here? (I'm not suggesting necessarily using those precise colors, but they seem like a decent example of not-too-dark colors that are very distinct (to my eye) and that look quite nice.
