Input/Output
Parsed input and string output formats support all valid CSS forms in addition to allowing the color() function format as well using the custom name --oklab.
oklab(l a b / a) // Oklab function
color(--oklab 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("oklab", [0, 0, 0], 1)
The string representation of the color object will always default to the color(--oklab l a b / a) form, but the default string output will be the oklab(l a b / a) form.
>>> Color("oklab", [0.62796, 0.22486, 0.12585])
color(--oklab 0.62796 0.22486 0.12585 / 1)
>>> Color("oklab", [0.79269, 0.05661, 0.16138]).to_string()
'oklab(0.79269 0.05661 0.16138)'
>>> Color("oklab", [0.96798, -0.07137, 0.19857]).to_string(percent=True)
'oklab(96.798% -17.842% 49.643%)'
>>> Color("oklab", [0.51975, -0.1403, 0.10768]).to_string(color=True)
'color(--oklab 0.51975 -0.1403 0.10768)'
