Hey, I just released a new update that adds multiple color schemes to help with colorblindness! At some point I may add a color blind mode that does away with the need for colors altogether, but for now this should make things a bit better. Also, there is now a gauge next to the board so you can more easily see the range of colors (unfortunately, it doesn't yet work on Firefox).
Check it out!
I also skipped forward a day, so if you already played today you can play again with the next word to try it out.
Ah, the other color schemes look really good (especially I like the heatmap one). However, the default stoplight one is nearly impossible for me to disambiguate. For example, in [1], I can't tell which of mine are closer at all (I don't think I am colorblind, but maybe I'm just in for a surprise today).
Anyway, overall, a very fun variant. Thanks for sharing!
