About this tool
Enter a colour once and read it back in every format you need. Type a HEX, RGB, HSL or CMYK value — or grab one with the native colour picker — and the other fields update in real time, all kept in sync. Click any value to copy it. Everything is computed in your browser with no round-trip to a server, so it is instant and private. Open Advanced options to see the nearest colour name and the WCAG contrast ratio of the colour on white versus black.
