Erich Heckel sits in the centre of the value range, lending the palette a sense of even, sustained light. Erich Heckel keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. #BBAE3C functions as the palette's exclamation mark: highest chroma, lowest percentage (5.6%). A value spread of 56 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette reads as an Impressionist one - light-biased, chromatically direct, and built on temperature contrast rather than value opposition. This is palette 4 of Erich Heckel's sequence - a single chapter in a chromatic story told across many works.
