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!
