Off-topic: who is in charge of choosing colors for graphs? Being red-green colorblind, choosing blue and purple is makes it impossible for me to read the charts. I know its stylish, but every time i make a graph i choose very high contrast colors. Another point: is it just being color blind or do other people struggle in charts/maps that have shades of a color? like different shades of blue represent different rates of covid deaths across a map. just curious if anyone else struggles with this
