Why Test for Color Blindness?
Approximately 8% of men and 0.5% of women worldwide have some form of color vision deficiency (CVD). If your design relies solely on color to convey information (like error states or charts), a significant portion of your audience might not understand it.
- Ensure text is readable against backgrounds.
- Verify that charts and graphs are distinguishable.
- Check if call-to-action buttons stand out.
Types of Color Blindness
Deuteranopia (Green-Blind)
The most common form. Greens look red/brown. 6% of males have this.
Protanopia (Red-Blind)
Reds look dark or greenish. Affects about 2% of males.
Tritanopia (Blue-Blind)
Very rare. Hard to tell blue/green and yellow/violet apart.
