About Color Blindness
Affects ~8% of men worldwide.
Red-green deficiency is most common.
What is Professional Color Blindness Simulator & Accessibility Auditor?
Design with empathy and inclusivity using our Professional Color Blindness Simulator. Approximately 8% of men and 0.5% of women worldwide experience some form of color vision deficiency (CVD). This utility allows you to instantly preview how your color choices appear to users with Protanopia, Deuteranopia, Tritanopia, and other rare conditions. Ensure your UI elements, data visualizations, and branding are accessible to everyone by identifying potential 'color-clashes' before they reach production.

Game Design Auditing
Preview game assets to ensure crucial feedback loops are visible without specialized colorblind modes.
FAQs
What is color blindness?
Color blindness (color vision deficiency) is the decreased ability to see color or differences between colors.
How does this simulator work?
The simulator uses mathematical algorithms to transform RGB color values based on how different types of color blindness affect cone cells.
