The high-key values of Claude Monet give it an effulgent, almost bleached quality. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #978557, registers at 3.8% - sparse enough to feel like a deliberate surprise. Value range is moderate at 42 units - enough contrast for legibility, not so much as to fragment the tonal unity. 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 Claude Monet's complete body of work advances.
