FAQ
What percentage of people are affected by color blindness?
Roughly 8% of men and 0.5% of women of Northern European descent have some form of red-green color blindness, making protanopia and deuteranopia the most common types to design for.
Should I rely on color alone to show status?
No. Even with a color-blind-safe palette, pair color with icons, labels, or patterns so status is never communicated by color alone.
