Loon's color list is used to map nominal values to colors. See
the documentation for l_setColorList.
l_setColorList_hcl(chroma = 56, luminance = 51, hue_start = 231)The chroma of the color. The upper bound for chroma depends on hue and luminance.
A value in the range [0,100] giving the luminance of the colour. For a given combination of hue and chroma, only a subset of this range is possible.
The start hue for sampling. The hue of the color specified as an angle in the range [0,360]. 0 yields red, 120 yields green 240 yields blue, etc.
Samples equally distant colors from the hcl color wheel. See the
documentation for hcl for more information.
