Values in Camille Pissarro rest in the mid-range - neither dramatically lit nor steeped in shadow. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The saturated accent, #795632, registers at 8.7% - sparse enough to feel like a deliberate surprise. The full value range is 64 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 15 sits within the larger chromatic argument that Camille Pissarro's complete body of work advances.
