Adjacent rectangular strip palettes help me see how one color can appear different when placed next to another. The little circles look pretty, but are too small and too far apart to judge color. I would also like the option to change the background on the palettes to white, black or neutral gray. I think this would greatly assist in color visualization on the fly. Right now I make my palette squares on a separate document and change the background there. It would be more efficient to do this on the palette.
