Ah yeah, supporting w3c standards is probably a sensible move.

I think it can be interesting to provide some string formats can be directly converted into color structures.

For example :
 - plain color names : "red", "blue", "light gray",...
 - hexadecimal : "#FF3CBB", "#FF3CBBAA" (same with alpha)
 - decimal : "255, 158, 200", "255, 158, 200, 170"
...

I think to that cause I saw many times tools using pretty close syntax for color definitions but with boring variations (generally for the alpha position).

It is defined in a w3c standard and refined in a draft, but probably does not belong in the colour module, but a media-file parser module?

However, the at least the following colour spaces are mentioned as supported in w3c documents:

L*ab, L*CHab, HSL, HWB
