The high-key values of Alfred Wallis give it an effulgent, almost bleached quality. 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. Alfred Wallis gives 38.5% of the composition to a single #D5C4AD - a decisive chromatic anchor. #B7A991 at 6.1% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. From deepest dark to palest light, the palette traverses 59 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Alfred Wallis's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
