The value structure of Vincent van Gogh is mid-key: quiet, controlled, and cohesive. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #180F0E at 25.2% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The most saturated colour, #864F2E, is reserved to 7.6% of the surface, where it acts as a focal punctuation. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. In the context of Vincent van Gogh's full range of palettes, group 28 represents one movement in an ongoing chromatic dialogue.
