A common task for designers is to select a subset of colors (''qualitative'' colormap) that are as mutually differentiable as possible ([[Color coding in data visualization#Choosing salient colors for color coding|salient]]). For example, player pieces in a [[board game]] should be as different as possible.

Classic advice suggests using [[Cynthia Brewer#Brewer palettes|Brewer palettes]],{{citation needed|date=December 2024}} but several of these are not actually accessible to the color blind.{{which|date=December 2024}}

An issue with color selection is that the colors with the greatest [[Contrast (vision)|contrast]] to the [[#Red–green color blindness|red–green color blind]] tend to be [[#Confusion colors|colors of confusion]] to the [[#Blue–yellow color blindness|blue–yellow color blind]] and vice versa.

In 2018, [[user experience|UX]] designer Allie Ofisher published 3 color palettes with 6 colors each, distinguishable for all variants of color blindness.<ref>{{cite web|url=https://medium.com/@allieofisher/inclusive-color-palettes-for-the-web-bbfe8cf2410e|title=Inclusive Color Palettes for the Web|author=Allie Ofisher|website=Medium|date=18 May 2018|access-date=17 Dec 2024}}</ref>{{Self-published inline|date=December 2024}}
