Illustrative Material for the Munsell Color System

Color Atlas

The Atlas is composed of charts whose measured scales of hue, value, and chroma are made in solid pigment colors, tested and chosen for permanence. The scales are stand- ardized by five basic colors preserved in vitreous enamel and recorded in terms of wave-length and degree of white light.

The charts bear appropriate symbols on each step of their measured scales, so that any color or group of colors may be recorded and reproduced at will. Such records are valuable, not only in the study of color harmony, but also as a necessary means of reference in scientific and industrial lines, and are used in many schools, colleges, and laboratories. (See appendix to Chapter II.)

Model of The Color Sphere

This rotating sphere demonstrates the balance of color. It gives the child not only a clear mental grasp of measured relations, but also prepares the way for noting and preserv- ing a record of such combinations as give harmony or discord. ;

Model of The Color Tree

This tangible image of color relations worked out from the scales of the Atlas is a great aid to color study, serving to locate and name a color, as the school globe locates and names a place. Those to whom color has remained somewhat of a mystery may gain from this model a clear understanding of color qualities and quantities.
