Yes, Ben. That's exactly what I needed. As it turns out I meant addition table, not times, but that just means changing the * to +. I was inspired by Linda's addition tables (for first graders that I have been working with), but I could not properly appreciate the purpose of the colors relative to the underlying numeric magnitudes. In retrospect, I can see the parallel anti-diagonals in the RGB palettes better, but not the continuity in the main diagonal, like I can see in the greyscale.
