How do I check if my team colors are colorblind-friendly?

Enter your colors and the simulator shows how they appear under protanopia, deuteranopia, and tritanopia, so you can confirm they stay distinct for every viewer.

What is the most common type of color blindness?

Red-green deficiency (protanopia and deuteranopia) is by far the most common, affecting roughly 1 in 12 men, which is why distinguishable team colors matter.

Most common risk: Deuteranopia

~6% of men can't distinguish red from green. If your primary and secondary colors look similar under deuteranopia, a meaningful portion of your fanbase can't tell them apart — or distinguish you from opponents with similar palettes.

How to design inclusively

Ensure at least one color pair is distinguishable in grayscale
Avoid red + green as your only two primary colors
Use lightness contrast — not just hue — as your main differentiator
Test jersey vs. opponent colors under deuteranopia
