The high-key values of El Lissitzky give it an effulgent, almost bleached quality. Temperature is cool-dominant, with blue and green families claiming the largest areas. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. 37.7% of the palette belongs to #E5DFD5, a concentration that makes it the unmistakable visual centre. The saturated accent, #CFA844, registers at 1.0% - sparse enough to feel like a deliberate surprise. The value range spans 71 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 4 sits within the larger chromatic argument that El Lissitzky's complete body of work advances.
