Otto Marseus van Schrieck is built on dark foundations, with values clustered toward shadow. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #090404 at 41.2% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. Only 2.1% is devoted to #D7C48D, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 70 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. Palette 4 sits within the larger chromatic argument that Otto Marseus van Schrieck's complete body of work advances.
