Convert OKLab color values into standard RGB channels.

Input formats

Provide colors using oklab(L a b) syntax, with lightness as a percentage from 0% to 100% and the a and b axes as small plain numbers. Each line is parsed independently in batch mode.

RGB output

The output prints as rgb(r, g, b) with each channel from 0 to 255. oklab(68.04% 0.1747 0.1165) becomes rgb(255, 87, 51).

Out-of-gamut values

Not every OKLab value maps to a color inside sRGB. When a and b push a color beyond that range for the given lightness, each RGB channel clamps to 0-255, which can shift the result slightly from the exact OKLab value entered.

Frequently Asked Questions

What OKLab format does it accept?

oklab(L a b) with L as a percentage (or a 0-1 number) and a/b as small plain numbers, such as oklab(68.04% 0.1747 0.1165). Paste one color per line for batch conversion.

Can every OKLab value be converted to a valid RGB color?

No. OKLab can describe colors outside the sRGB gamut a browser can display. Out-of-gamut results are clamped to the nearest representable channel values.

Do I need to specify L as a percentage or a decimal?

Either works. A trailing percent sign is read as 0-100%, and a plain number is read directly on the 0-1 scale the CSS oklab() function also accepts.
