Color vision deficiency (color blindness) affects approximately 8% of males and 0.5% of females worldwide. This tool simulates how images appear to people with different types of color vision deficiency.
About this tool
Color blindness, or color vision deficiency, affects millions of people worldwide and can significantly impact how they perceive digital interfaces, images, and visual content. This simulator allows you to preview how colors appear to individuals with different types of color vision deficiency—including red-green blindness, blue-yellow blindness, and complete monochromacy—helping you understand accessibility challenges and design more inclusive digital experiences.
To use the simulator, simply upload an image or paste a color value, select the type of color vision deficiency you want to simulate, and the tool will instantly show you how that image or color appears to someone with that condition. This is invaluable for designers, developers, and content creators who want to ensure their work is accessible to everyone, not just people with typical color vision.
The tool uses scientifically-backed color transformation algorithms based on research into how color-blind vision actually works. Keep in mind that individual perception varies and this simulator provides a representative approximation rather than an exact match to every person's experience. It's an excellent starting point for accessibility testing and inclusive design.
