HPLuv 3D — Figure 1. HPLuv color space in 3D

HPLuv is similar to HSLuv but takes as many colors as it can from CIELCh_uv without distorting the chroma. This ends up reducing the gamut to a subset of the sRGB gamut. In the end, only more pastel colors remain.

Inputs/Output

HPLuv is not currently supported in the CSS spec, the parsed input and string output formats use the color() function format using the custom name --hpluv:

color(--hpluv h p 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("hpluv", [0, 0, 0], 1)

The string representation of the color object and the default string output use the color(--hpluv h p l / a) form.

>>> Color("hpluv", [23.881, 100, 53.237])
color(--hpluv 23.881deg 100 53.237 / 1)
>>> Color("hpluv", [49.45, 100, 74.934]).to_string()
'color(--hpluv 49.45 100 74.934)'
