Childe Hassam is high in key: pale, luminous, and filled with optical air. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. 39.3% of the palette belongs to #E6E7E6, a concentration that makes it the unmistakable visual centre. At 5.4%, #6F5138 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 63 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. In the context of Childe Hassam's full range of palettes, group 15 represents one movement in an ongoing chromatic dialogue.
