Colorblind Simulator
Preview how colors and uploaded images appear under multiple forms of color-vision deficiency before you publish a design.
Best For
Use Colorblind Simulator when you need to make color decisions with clear previews, conversions, and accessibility checks. The page is designed around a focused workflow: bring in the color value, palette, or reference image, make the adjustment or check, then copy the final values into your stylesheet, design system, or production file.
Most work happens locally in your browser, which keeps files and text on your device and makes quick repeat checks practical. Review the output, then copy the final values into your stylesheet, design system, or production file.
