Values in Joan Brull 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. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #807F51, registers at 6.9% - sparse enough to feel like a deliberate surprise. Spanning 46 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. In the context of Joan Brull's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
