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.
