Joan Brull sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #1E3E54 functions as the palette's exclamation mark: highest chroma, lowest percentage (10.3%). The full value range is 61 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 11 sits within the larger chromatic argument that Joan Brull's complete body of work advances.
