What is the best color for a colorblind person?
Blue (and orange)
Note that the color that looks the most the same for people with normal vision and readers with red-/green-blindness (the most common types of colorblindness) is blue. “Blue is the safest hue.” If you want red- and green-blind readers to perceive color as you do, choose blue.
Is pink colorblind friendly?
Meanwhile, common colorblind friendly palettes like magenta/green or orange/purple are devoid of meaning. Pink, for example, doesn't convey negativity like red does. Others, like blue/red, are already imbued with too much cultural meaning and would be confusing in a non-political map.
