Input/Output
Linear A98 RGB is not supported via the CSS spec and the parser input and string output only supports the color() function format using the custom name --a98-rgb-linear:
color(--a98-rgb-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("a98-rgb-linear", [0, 0, 0], 1)
The string representation of the color object and the default string output will be in the color(--a98-rgb-linear r g b / a) form.
>>> Color("a98-rgb", [0.71513, 0, 0])
color(a98-rgb 0.71513 0 0 / 1)
>>> Color("a98-rgb-linear", [0.82231, 0.37626, 0.01549]).to_string()
'color(--a98-rgb-linear 0.82231 0.37626 0.01549)'
