Low-key values are the structural spine of Gustave Courbet, giving it gravity and atmosphere. Yellow, ochre, sienna: warm hues that Gustave Courbet deploys as the palette's primary energy. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. A single dominant - #1B1712 at 33.9% - sets the character of the whole composition. The saturated accent, #C19F4E, registers at 1.1% - sparse enough to feel like a deliberate surprise. The palette spans 51 value units: a measured range that delivers coherence over drama. Together these qualities place Gustave Courbet firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. Gustave Courbet's palette 16 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
