We went with the image approach so that the colors are still visible in high contrast mode. If the actual colors are a problem, the user can then turn off images and use the alternative or title text for the image. There is also not a separate image for each color - just a blank image which is reused for spacing/layout and an overlay image of the entire grid of colors.

Rendering limitations? Cross-browser-compatibility? 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?

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 this be multi-selectable.
