Childe Hassam is high-key - luminous, open, and weighted toward light. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. #EDDEB9 at 29.5% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. At 5.1%, #A2702E carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 63 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. 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 1 represents one movement in an ongoing chromatic dialogue.
