<h3>Details</h3>

<p>The HCL (hue-chroma-luminance) color model is a perceptual color model
obtained by using polar coordinates in CIE <code>LUV</code> space
(i.e., <code>polarLUV</code>), where steps of equal size correspond to
approximately equal perceptual changes in color. By taking polar coordinates
the resulting three dimensions capture the three perceptual axes very well:
hue is the type of color, chroma the c
