Color-Intensities in Different Values
133. If we proceed to carry out the idea of Diagram 2, producing all the twelve colors in all of the seven values intermediate between the extremes of Black and White, making the colors, in every case, as strong, as intense, as is possible with the pigment-materials we have chosen to use, we shall discover that the twelve colors reach their greatest intensities in different values; that is to say, in different quantities of light. Red reaches its greatest intensity in the value High Dark, Orange in Low Light, Yellow in High Light, Green in Low Light, Blue in High Dark, Violet in Low Dark, approximately; and the intermediate colors reach their greatest intensities in the intermediate values, approximately. In order to indicate this fact in our diagram, we will mark the positions of greatest intensity by putting the color signs in larger type.
