Inputs/Output
ACEScct is not supported via the CSS spec and the parser input and string output only supports the color() function format using the custom name --acescct:
color(--acescct 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("acescct", [1, 0, 0], 1)
The string representation of the color object and the default string output will be in the color(--acescct r g b / a) form.
>>> Color("acescct", [0.51451, 0.33604, 0.23515])
color(--acescct 0.51451 0.33604 0.23515 / 1)
>>> Color("acescct", [0.53009, 0.48237, 0.32561]).to_string()
'color(--acescct 0.53009 0.48237 0.32561)'
