Jules Breton distributes its values across the middle register, creating harmony without high contrast. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #8A7558, registers at 7.9% - sparse enough to feel like a deliberate surprise. 61 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Jules Breton's full range of palettes, group 13 represents one movement in an ongoing chromatic dialogue.
