👁️ Color Blind Simulator
Simulate how colors appear to people with different types of color blindness: Protanopia, Deuteranopia, Tritanopia, and Achromatopsia.
Color Blindness Simulator
The Color Blind Simulator allows designers and developers to preview how their color choices appear to people with various types of color vision deficiency. Approximately 8% of men and 0.5% of women worldwide have some form of color blindness, making this an essential consideration for inclusive design.
This tool simulates five vision types: Normal vision, Protanopia (red-blind), Deuteranopia (green-blind), Tritanopia (blue-blind), and Achromatopsia (total color blindness). Each simulation uses an SVG color matrix filter that accurately approximates the color perception of each condition.
By testing your color palette with this simulator, you can identify potential accessibility issues before they affect your users. This is especially important for data visualizations, status indicators, and form validations that rely on color alone to convey information.
Frequently Asked Questions
What is Protanopia?
Protanopia is a type of red-green color blindness caused by the absence of red cone cells. People with protanopia have difficulty distinguishing between red, green, and some yellows, and reds may appear darker.
What is Achromatopsia?
Achromatopsia, also known as total color blindness, is a rare condition where a person sees no color at all. The world appears in shades of gray, similar to a black-and-white photograph.
How does this simulator work?
This tool uses SVG feColorMatrix filters to transform the selected color according to color vision deficiency simulation matrices. These matrices are based on established research on how color information is processed by the human visual system.
