Input/Output
As a D65 variant of CIELCh is not currently supported in the CSS spec, the parsed input and string output formats use the color() function format using the custom name --lch-d65:
color(--lch-d65 l c h / 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("lch-d65", [0, 0, 0], 1)
The string representation of the color object and the default string output use the color(--lch-d65 l c h / a) form.
>>> Color("lch-d65", [53.237, 104.55, 40])
color(--lch-d65 53.237 104.55 40 / 1)
>>> Color("lch-d65", [74.934, 82.499, 73.14]).to_string()
'color(--lch-d65 74.934 82.499 73.14)'
