RE: Creating a color palette

We at SAP would try first focuseable cells with background coloring and
title attribute filled and no images (except mayby a non-focuseable
spacer.gif for layout, but   will do the job also, I think), so,
why having discrete images for each color? Rendering limitations?
a plus for clickable image map is that it allows for non-rectangle
shaped color-selection maps. what about having/demanding for
keyboard-navigable image-maps?

	We had this call. The color palette should be a grid with cell
navigation. Each grid cell should have an image with title text
containing a translatable color, like red, and the RGB value.

	If you are picking colors from a discrete palette, you might
consider a
	role of 'select' since it doesn't sound as though you would let
	be multi-selectable.
