Albert Herter is high-key - luminous, open, and weighted toward light. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #8F6D5B, is reserved to 3.2% of the surface, where it acts as a focal punctuation. At 41 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. In the context of Albert Herter's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
