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.
