The high-key values of self-portrait give it an effulgent, almost bleached quality. The palette tilts toward cool - blues and silver-greys carry the structural weight. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #362723, is reserved to 4.0% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 57 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
