Oil-Painting is simplified by three new pigments, perfected by Dr. Herbert E. ives of the Bell Telephone Laboratories, which yield any color of the rainbow when mixed. Hitherto, artists have had to employ dozens of pigments, and learning how to use them has required long training. in theory, only three "primary colors" should meet the needs, but these were mistakenly supposed to be blue, yellow, and red, which gave unsatisfactory results. Actally, Dr. ives finds, the true primary colors for pigments are turquoise, yellow and crimson, of hues meeting rigid spectroscopic tests. Colors prepared from his specifications have been found sufficient for any artist's palette. He has devised a chart and viewing screen to show how to match any shade.
