So, with the risk-laden legacy of having pointed out the failure of others to consider colorblindness when choosing data-driven colors schemes, I went ahead and picked a couple of "contrasting" colors that are virtually identical when wearing goggles of the two most common types of colorblindness...
A cutout from the original (check out the full image here)...
The baffling oblivion as seen by one who possesses deuteranope vision...
The less ridiculous but still largely useless incarnation as seen through protanope eyes...
Crow eaten. Ah well.
I'm a colorblind (well color "deficient") dude and it peeves me no end when designers encode essential data using close shades of red, green, or brown, with no alternative like title tags. Thanks for thinking of us!
