A. Use of One Color with Black and White.

The use of red for emphasis on a black and white page is effective because of brightness, intensity and high contrast combined with a wave length on which the eye can focus easily at about reading distance.

These colors differ in chroma.

B. All Colors Differ in These Three Ways.

A very fine summary of Ostwald's (1853-1932) color theory and system appeared in "The Science of Color," More Business, * November, 1937, written by Egbert G. Jacobson, President, Association for Color Research. The interrelation of hues is beautifully shown throughout the color solid with unusual accuracy and richness.

Faber Birren follows Ostwald with modifications, using a 13-26 hue circle instead of Ostwald's 12-24. or Munsell's 5-10 circles. His chart gives the natural intervals between hues as seen by the human eye. Printing inkstand tempera colors^in these hues are available commercially. All color charts are good if used intelligently.
