In earlier work the writer presented a graphic technique for summarizing information about the colors resulting from pigment mixture, along with data for the pigments of a selection at lightness 9 of a 10-step scale. Similar information about the colors resulting from mixture of the same pigments at lightnesses 7, 5, 3, and 1 of the same scale is presented here. This shows that by using different positions for some pigments at different lightnesses, information about the colors resulting from mixture of the pigments at these lightnesses also can be summarized very well in graphic form. A technique for assembling the pigment positions for all the given lightnesses on a single diagram is introduced.
