Input/Output
The CAM02 SCD space is not currently supported in the CSS spec, the parsed input and string output formats use the color() function format using the custom name --cam02-scd:
color(--cam02-scd j a b / a) // Color function
The string representation of the color object and the default string output use the color(--cam02-scd j a b / a) form.
>>> Color("cam02-scd", [60.054, 31.859, 20.029], 1)
color(--cam02-scd 60.054 31.859 20.029 / 1)
>>> Color("cam02-scd", [79.041, 8.4908, 26.699], 1).to_string()
'color(--cam02-scd 79.041 8.4908 26.699)'
