Erich Heckel sits in the centre of the value range, lending the palette a sense of even, sustained light. Erich Heckel tilts toward cool - blues and silver-greys carry the structural weight. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. Only 10.0% is devoted to #D6A84F, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 56 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Taken together, these qualities constitute Erich Heckel's chromatic voice - distinctive enough to be read across an entire body of work.
