Accessibility and the graphics stack

Accessibility and the graphics stack

Since the talk and article start off by using gnuplot output as an example of poor accessibility, I'd like to point out that gnuplot's default color scheme has changed in version 5 (2nd release candidate out for a couple of months now) to one derived from the set of colors recommended by Wong [Nature Methods 8, 441]. Wong's colors are specifically chosen to be distinguishable by color-blind individuals with either protanopia or deuteranopia. But it's also worth noting that any color choice needs to be re-checked after it has been converted/mangled/repurposed into the final output medium. The colors used for a beamer projection may or may not work if printed on a CMYK printer, and so on.

Has there been any thought about providing standard sets of accessible colors with appropriate tags for output medium? Some sort of virtual color library?
