The value structure of Agnes Goodsir is mid-key: quiet, controlled, and cohesive. Agnes Goodsir 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. #171B1B at 33.2% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. At 4.9%, #563730 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range spans 64 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Agnes Goodsir's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
