Have you tried the EnChroma color-blindness glasses? It would be an easier solution than designing data viz to avoid using color blindess color-combos or requiring dynamic options, IMO.



Those work best when your color-blindness is from your red/green cones being too close together in wavelength (most common form) and not for cases like me where color sensitivity is screwed up. The sensitivity problem can be solved by filtering the colors working correctly down to the level the bad color works at, but that doesn't work well indoors as you are effectively wearing sun-glasses.

The easiest way I found for data viz to accommodate color blindness is to make sure everything is separated in intensity by a fair amount and have a tool-tip on the color legend indicating which color it is so if the accompanying text is referring to parts by color it can be figured out which color on the graph is being referred to.


It's really not that hard to design for colorblindness, since there majority of colorblindness is one type. Blue/red instead of green/red is a pretty easy color swap.
