Tool guide

Convert color values and inspect contrast

Convert HEX, RGB, HSL and other color representations, with previews and reference contrast values against black and white.

How to use

Enter a valid color value.
Copy a target format and review it on the actual background.

Example and expected result

Input: #ff0000
RGB: rgb(255, 0, 0)
HSL: hsl(0, 100%, 50%)

Capabilities and limits

CMYK values are not ICC-managed print proofs.
A contrast value is not a full interface accessibility audit.

Troubleshooting

Check parentheses, percentages and ranges for invalid colors. A nearest color name may not exactly match the input.

Data processing and storage

Color conversion happens in page state without image uploads or screen-color capture.
