The essential point is that weaknesses in the implementation of an idea are
not a good reason to throw out the idea itself.

	    My preferred paint palette is the whole screen anyway.  I wouldn't
	    use a menu.  I'd just let you pick any color on the screen.

That's a cheap shot made possible by using a quote in isolation.  In the
sentence before this I described a way to provide full color menus.  I was
merely stating my preference.  I would never let my preferences
be a justification for not providing mechanism.

Having 2^24 colors on a menu would be totally impractical even
if it were possible (there aren't enough pixels on the screen to display
all those colors at once).  However your real question here, "how do you
get colors if you don't have much on your screen", is a good one.  The
answer is a simple tool to display the color map.

Let's continues any further discussion privately.  This debate has already
degenerated too far toward a childish "yes it is, no it isn't" style.
