The high-key values of self-portrait give it an effulgent, almost bleached quality. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The dominant colour, #E3DFD3, takes 30.6% of the total area, establishing the overall mood before any other hue is introduced. The highest-chroma note - #0F1718 - appears at just 0.8%, deployed as a precision accent against the quieter ground. 73 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
