Color Vision Accessibility

Simulate color-vision deficiencies and check contrast ratios to ensure your designs are accessible to everyone.

How It Works

Get instant feedback on your design's accessibility in three simple steps.

STEP 1

Drag and drop any image file (screenshots, mockups, or graphics) to get started.

STEP 2

Choose from protanopia, deuteranopia, tritanopia, or achromatopsia with adjustable severity.

STEP 3

View side-by-side comparisons and apply Daltonization filters to improve accessibility.

Test your designs against different types of color vision deficiencies with precise control and instant visual feedback.

■

Simulate red-blindness affecting approximately 1% of men. Test how your designs appear to users with reduced sensitivity to red light.

●

Experience green-blindness, the most common form of color vision deficiency. Ensure your green elements remain distinguishable.

▲

Test for blue-blindness, a rare but important condition. Verify that blue elements in your design remain accessible.
