create a 3-D scatter plot of colors
list of colors in formats recognized by ColorTools or a Palette object
(optional) equation(s) of the form option=value where option is one of space, symbol, or displayable
space=string designating a known color space
Use the specified color space instead of "Lab". All color spaces 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.
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 SpatterPlot3d command renders a scatter plot of colors by their chromatic dimensions. The point for each color is a randomly chosen shape.

The following commands read an image and extract its pixels as RGB colors.

Scaling is important here to reduce the total number of colors in the plot.
