Values in Charles Cottet rest in the mid-range - neither dramatically lit nor steeped in shadow. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 4.7% is devoted to #C78851, yet that small allocation delivers the palette's entire chromatic tension. Spanning 54 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Charles Cottet's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
