Blindness Simulator
Check how a color is perceived by people with different types of color blindness to create more accessible designs. Understanding color perception helps ensure your content is accessible to everyone.
Impact
8% of men and 0.5% of women have some form of color vision deficiency.
Types
Red-green blindness is most common, affecting how reds and greens are perceived.
Design Better
Use contrast and patterns alongside color to convey information.

Note: These simulations are approximations. Actual color perception may vary between individuals with the same type of color blindness.
Understanding Color Blindness
Create inclusive designs by testing color accessibility
Color blindness affects approximately 1 in 12 men and 1 in 200 women worldwide. This simulator helps designers, developers, and content creators understand how their color choices appear to people with various forms of color vision deficiency.
By testing your colors through different color blindness simulations, you can ensure your designs are accessible and effective for all users. This tool simulates the most common types of color vision deficiency including Protanopia, Deuteranopia, Tritanopia, and complete color blindness.
Why It Matters
Color alone should never be the only way to convey information. Testing with this simulator helps identify potential issues.
Use Cases
Perfect for UI design, data visualization, branding, and any visual content that relies on color differentiation.
