How it works

1Paste a colour in any form — a hex, rgb(…), hsl(…), oklch(…), or a CSS name like rebeccapurple.

2Leave the reader on Detect unless you are pasting bare numbers, in which case pick the notation.

3Convert, then copy whichever row you need.

4HEX, RGB, HSL, HSV, LAB, LCH, OKLAB and OKLCH all round-trip exactly; CMYK and YCbCr are one-way approximations, so they are output only.
