space=string designating a known color space

Use the specified color space instead of "Lab". "Luv" and "xyY" work well.

symbol="box", "circle", or "diamond"

Specify a symbol in order to use only that respective shape for points, instead of the random shapes.

displayable

If specified ColorTools:-ToDisplayable will not be called for the colors sent to plot.  This should improve performance but will also cause non-displayable color points to be displayed as white.

The SpatterPlot command renders a scatter plot of colors by their chromatic dimensions. The point for each color is a randomly chosen shape, with its size given by the lightness of the color. For colors given by Color objects or strings, a plot annotation will be created for its point.

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