The perfect lead into my series on perceptual color palettes. Great post!
I thought it’d be interesting to run a simulation of what the map would actually look lie to viewers with the 3 types of color deficient vision. Below are my results for the first map. It is obvious from this simulation that while the map is OK for Tritanope viewers, the green and red areas are very confusing for Protanope and Deuteranope viewers.
The second map instead passed the simulation tests. Here I am showing the original at the top and the Deuteranope simulation at the bottom.
