Boris Kustodiev is high in key: pale, luminous, and filled with optical air. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. A single dominant - #F1FAF5 at 31.5% - sets the character of the whole composition. #B06E32 functions as the palette's exclamation mark: highest chroma, lowest percentage (1.0%). The value range spans 82 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Boris Kustodiev's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
