Perhaps your imagination is lacking; I've been around for a while, I  
think, yet I (still) have no answer to Roger's post.

There's nothing in your Manipulate (or in Help for RGBColor) to indicate  
the number of colors available.

Just because you've stepped your controls in units of 1/256 doesn't mean  
the unit matters to RGBColor.
