Ulrihs Boitmanis is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #9A6A24 functions as the palette's exclamation mark: highest chroma, lowest percentage (1.6%). The value range spans 56 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Ulrihs Boitmanis's sequence - a single chapter in a chromatic story told across many works.
