Input/Output
Linear Rec. 2020 is not supported via the CSS spec and the parser input and string output only supports the color() function format using the custom name --rec2020-linear:
color(--rec2020-linear r g b / a) // Color function
When manually creating a color via raw data or specifying a color space as a parameter in a function, the color space name is always used:
Color("rec2020-linear", [0, 0, 0], 1)
The string representation of the color object and the default string output will be in the color(--rec2020-linear r g b / a) form.
>>> Color("rec2020-linear", [0.6274, 0.0691, 0.01639])
color(--rec2020-linear 0.6274 0.0691 0.01639 / 1)
>>> Color("rec2020-linear", [0.7513, 0.41509, 0.04951]).to_string()
'color(--rec2020-linear 0.7513 0.41509 0.04951)'
