Frequently asked questions
What types of color blindness are simulated?
▾
Protanopia (red-blind), Deuteranopia (green-blind), Tritanopia (blue-blind), and Achromatopsia (complete color blindness). Protanopia and Deuteranopia are the most common, affecting ~1% of males each.
How accurate is the simulation?
▾
The simulation uses linearized RGB color transformation matrices based on the Viénot method. It is a good approximation but may differ from clinical-grade simulations.
How can I use this for accessibility?
▾
Test your brand or UI colors through each simulation to ensure sufficient contrast and distinguishability for color-blind users. Pair it with the Color Contrast checker.
