The value structure of George Washington Lambert is mid-key: quiet, controlled, and cohesive. 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. Only 4.4% is devoted to #678FB1, yet that small allocation delivers the palette's entire chromatic tension. The value range of 47 units sits in the comfortable middle: enough depth, enough light, neither extreme. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 1 sits within the larger chromatic argument that George Washington Lambert's complete body of work advances.
