Childe Hassam keeps values measured and balanced, a hallmark of tonal restraint. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #905135, registers at 3.5% - sparse enough to feel like a deliberate surprise. The full value range is 55 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Childe Hassam's full range of palettes, group 20 represents one movement in an ongoing chromatic dialogue.
