Gustave Courbet is high-key - luminous, open, and weighted toward light. Gustave Courbet 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. The most saturated colour, #67483F, is reserved to 4.8% of the surface, where it acts as a focal punctuation. 71 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 5 sits within the larger chromatic argument that Gustave Courbet's complete body of work advances.
