The value structure of Arthur Lismer is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #244957 functions as the palette's exclamation mark: highest chroma, lowest percentage (5.0%). The full value range is 59 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. Arthur Lismer arrived at this balance through long practice; the palette carries the weight of that experience.
