Mid-key values give Jules Breton its characteristic quietness - nothing blazes, nothing disappears. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #5B4B2A, registers at 12.2% - sparse enough to feel like a deliberate surprise. At 63 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Jules Breton's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
