18 months ago, after deciding to take the plunge and buy an A4000 
(which, by the way, is a fantastic machine!), I was disappointed in
the lack of applications which exploited the increased color capabilities
of 3.0/AGA.  I went about creating some simple, yet fun, graphics
programs with would exploit the color modes above 16 (see my Fractal,
Lyapunov Space, and Terrain uploads).

Then I realized that these graphics programs needed some type of palette 
control.

This need resulted in the creation of PaletteTool, the latest version
of which you are now reading about.

I decided that is was much better to implement the palette control for 
these applications as a separate utility, rather than embed it within
each program.  That way, the palette control could be used along with
any program which operates on a (default-able) public screen (like
the Workbench).

NOTE that PaletteTool can be used to alter the color palette of ANY
Workbench or default Public Screen which supports at least 8 colors.

It's functioning is NOT in any way dependant upon the presence of my 
Fractal, Lyapunov Space, or Terrain programs.

Regarding the "color by name" facility:  I don't know about you, but
I am terrible at trying to "roll my own" colors using RGB sliders!
