Charles-Francois Daubigny sits in the centre of the value range, lending the palette a sense of even, sustained light. Charles-Francois Daubigny tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 3.3%, #415628 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 64 units of value range, the palette has the tonal breadth to sustain complex spatial readings. 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 the light Charles-Francois Daubigny preferred, made measurable.
