Louise Elisabeth Vigee Le Brun keeps values measured and balanced, a hallmark of tonal restraint. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #91373C delivers the chromatic peak at only 3.4% - a small shot of colour with outsized visual impact. The full value range is 69 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 3 of Louise Elisabeth Vigee Le Brun's sequence - a single chapter in a chromatic story told across many works.
