color_parse_css

Attempts to parse a string describing an sRGB color in CSS notation.

This can be either a numerical representation (`rgb(255,0,0)` or `rgb(100%,0%,0%)`) or a hexadecimal notation as parsed by [ func@color_parse_hex] (`#ff0000`) or a color name as parsed by [func@color_parse_css] (`red`).

Additionally the `rgba()`, `hsl()` and `hsla()` functions are supported too.

Parameters:

css	a string describing a color in CSS notation

Returns:

a newly allocated [class@Gegl.Color] if css was parsed successfully, null otherwise
