If you like math you may be interested in my companion piece Optimizing Differentiability in Weighted-Frequency Color Coding at https://modalduality.org/posts/optimizing-color-coding/ https://modalduality.org/posts/optimizing-color-coding/ where I try to choose the most distinct colors, weighted by the number of speakers of the language.
