The value structure of Gerard de Lairesse is mid-key: quiet, controlled, and cohesive. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The highest-chroma note - #4F3223 - appears at just 6.7%, deployed as a precision accent against the quieter ground. The palette spans 49 value units: a measured range that delivers coherence over drama. These proportions encode Gerard de Lairesse's instinctive sense of how much of each quality the eye can hold.
