Leon Bonnat keeps values measured and balanced, a hallmark of tonal restraint. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. The most saturated colour, #47280A, is reserved to 11.0% of the surface, where it acts as a focal punctuation. 68 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. In the context of Leon Bonnat's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
