Bartolome Bermejo is built on dark foundations, with values clustered toward shadow. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Bartolome Bermejo gives 35.6% of the composition to a single #141212 - a decisive chromatic anchor. Only 3.0% is devoted to #DFD1A9, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 68 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. This is palette 4 of Bartolome Bermejo's sequence - a single chapter in a chromatic story told across many works.
