Color Blindness Simulator

See how a color appears to people with different types of color vision deficiency. Protanopia and deuteranopia affect red-green perception (the most common forms, affecting ~8% of men). Tritanopia affects blue-yellow perception. Achromatopsia is complete absence of color vision. Use this when designing to ensure your palette works for all users.
