Claude Monet is high in key: pale, luminous, and filled with optical air. Temperature is cool-dominant, with blue and green families claiming the largest areas. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. Only 12.1% is devoted to #987D38, yet that small allocation delivers the palette's entire chromatic tension. At 38 units across the value scale, the palette keeps contrast readable without letting it dominate. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 12 of Claude Monet's sequence - a single chapter in a chromatic story told across many works.
