Values in self-portrait rest in the mid-range - neither dramatically lit nor steeped in shadow. Built on cool foundations: the palette favours the blue-cyan-green arc. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. The dominant colour, #B3975A, takes 25.4% of the total area, establishing the overall mood before any other hue is introduced. Only 2.5% is devoted to #8E9A1A, yet that small allocation delivers the palette's entire chromatic tension. The value range of 50 units sits in the comfortable middle: enough depth, enough light, neither extreme. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
