Figure 1. Okhsl color space in 3D
Okhsl was created by Björn Ottosson and is a transform of the Oklab color space that approximates the sRGB gamut perceptually in an HSL color model. The aim was to create a color space that was better suited for being used in color pickers than the current HSL.

Input/Output
Okhsl is not currently supported in the CSS spec, the parsed input and string output formats use the color() function format using the custom name --okhsl:
color(--okhsl h s l / 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("okhsl", [0, 0, 0], 1)
The string representation of the color object and the default string output use the color(--okhsl h s l / a) form.
>>> Color("okhsl", [29.234, 1, 0.56808], 1)
color(--okhsl 29.234 1 0.56808 / 1)
>>> Color("okhsl", [70.67, 1, 0.75883], 1).to_string()
'color(--okhsl 70.67 1 0.75883)'
