I need to draw a two dimensional view of the HSV color wheel. I haven't the
foggiest as to where to start. Some type of gradient fill that can change
the tone perhaps. Thanks if someone knows how to do this.

Instead of drawing the wheel you may use this PostScript
program:

Rename as *.eps and open or place in RGB mode in PhS with
sufficient resolution.

Thank you. I had no idea I could use eps files like this! I was thinking I
was going to have to delve into scripting it myself. Thanks again.

Alan,

thanks for the feedback. If you want to improve the
resolution, the size of the small equally colored squares,
then simply increase the number 'n' by a text editor.

E.g. n=400 instead of 200.
