saturation=float

A number between 0 and 5 for the LCH saturation of the colors in the wheel. (The default is 0.66.) In the LCH space, saturation is the ratio of the lightness and chroma coordinates.

chroma=float

A number between 0 and 150 for the chroma value of the colors. If specified, this overrides the saturation option.

lightness=range

A range of numbers from 0 to 150 for the range lightness values in the wheel. (The default range is $0..100$.)

nolegend=true or false

If true this prevents a legend of the colors list from being added to the plot.  This is false by default for fewer than 10 colors and true for 10 or more.

The LCHColorWheel command renders a color wheel in the LCH color space. If a list of colors is provided, circles are drawn on the wheel corresponding to the approximate· positions of those colors in LCH space. For colors given by Color objects or strings, a plot annotation will be created for its point.

$\mathrm{with}\left(\mathrm{ColorTools}\right)\:$

$\mathrm{LCHColorWheel}\left(\left[''Red''\,''Green''\,''Blue''\,''Yellow''\right]\,\mathrm{nolegend}\right)$

$\mathrm{LCHColorWheel}\left(32\,\left[''Red''\,''Green''\,''Blue''\,''Yellow''\right]\,\mathrm{saturation}=0.35\right)$

$\mathrm{LCHColorWheel}\left(32\,\mathrm{chroma}=35\right)$

$\mathrm{LCHColorWheel}\left(32\,\mathrm{chroma}=35\,\mathrm{lightness}=65..150\right)$

The ColorTools[LCHColorWheel] command was introduced in Maple 18.
