Colour-blindness #1

Closed GiladAmar closed 2 years ago

GiladAmar commented 2 years ago

Do you have any suggestions as to which palette is more friendly with color-bind folk? Love the look myself, nor am I colour-blind, but thought this might be a handy addition for others.

Nice work:-)

The issue with CVD is that if I recall correctly, people who are affected can in the most extreme case only readily distinguish no more than 7 different colours (using chroma and hue, so including greys). This makes it vital to also use luminance and overall very hard to find enough sufficiently distinct colours at all.

I’m also working on a mathematically optimised palette for CVD that might arguably also be optimal for syntax highlighting but that might take a while.

Until then, there are a lot of hand-picked/manually optimized versions out there: From data visualisations there are Okabe-Ito (https://www.nature.com/articles/nmeth.1618) and Paul Tol’s palettes (https://personal.sron.nl/~pault/). For VSCode, simply put “color blind” in the extension search and there are a couple of options straight away.
