Mid-key values give Karl Hauptmann its characteristic quietness - nothing blazes, nothing disappears. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 5.0% is devoted to #A7CAD5, yet that small allocation delivers the palette's entire chromatic tension. 51 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light Karl Hauptmann preferred, made measurable.
