Input/Output
As DIN99o LCh is not currently supported in the CSS spec, the parsed input and string output formats use the color() function format using the custom name --lch99o:
color(--lch99o jz cz hz / 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("lch99o", [0, 0, 0], 1)
The string representation of the color object and the default string output use the color(--lch99o jz cz hz / a) form.
>>> Color("lch99o", [57.289, 49.915, 37.692])
color(--lch99o 57.289 49.915 37.692 / 1)
>>> Color("lch99o", [77.855, 43.543, 67.811]).to_string()
'color(--lch99o 77.855 43.543 67.811)'
