Making websafe colors safe for colorblind people

I just made the colors of my plotting framework safe for colorblind people (thanks to Paul Tol’s notes) and I want to share a very nice result I got: How to make the really websafe colors safe for colorblind people with minimal changes.

mostly websafe and colorblindsafe websafe but NOT colorblind safe

(the colorblind-safe colors are on the left, the original websafe colors on the right)

To do so, I turned to Color Oracle (for simulation of colorblindness directly on my screen) and Emacs rainbow-mode (for seeing the colors while editing the hex-codes - as shown in the screenshots above) and tweaked the color codes bit by bit, until they were distinguishable in the simulation of Deuteranopia, Protanopia and Tritanopia.
