Alfred Guillou sits in the centre of the value range, lending the palette a sense of even, sustained light. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #CEBC9F, is reserved to 10.0% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 60 units of the value scale - a span that creates natural depth. The palette is recognisably Alfred Guillou's own: particular in its temperature, chroma, and the economy of its brightest note.
