The high-key values of Jean-Étienne Liotard give it an effulgent, almost bleached quality. Jean-Étienne Liotard builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 1.3%, #2D4D54 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The palette spans 49 value units: a measured range that delivers coherence over drama. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 1 of Jean-Étienne Liotard's sequence - a single chapter in a chromatic story told across many works.
