Input/Output
As a D65 variant of CIELab is not currently supported in the CSS spec, the parsed input and string output formats use the color() function format using the custom name --lab-d65:
color(--lab-d65 l a 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("lab-d65", [0, 0, 0], 1)
The string representation of the color object and the default string output use the color(--lab-d65 l a b / a) form.
>>> Color("lab-d65", [53.237, 80.09, 67.203])
color(--lab-d65 53.237 80.09 67.203 / 1)
>>> Color("lab-d65", [74.934, 23.927, 78.953]).to_string()
'color(--lab-d65 74.934 23.927 78.953)'
