Catalog type History
Provenance Dr. Gunkel developed this color diagram to plot a person’s color vision thresholds to help identify the kind of defect leading to color blindness. Sir Isaac Newton’s chart had saturated colors around the periphery diminishing into white in the center. Any color is then represented by a unique point in the circle described by polar coordinates. But pigment colors may not be an adequate test of basic color sense, so Gunkel developed this color diagram.
