self-portrait works almost entirely in the lower half of the value scale, privileging depth over brilliance. Warmth dominates - the palette leans heavily on the yellow-orange-red arc of the colour wheel. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. At 6.0%, #4B2E25 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 54 units across the value scale, the palette keeps contrast readable without letting it dominate. Together these qualities place the palette firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display.
