The value structure of Realism is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. Only 7.4% is devoted to #6F4329, yet that small allocation delivers the palette's entire chromatic tension. Value range is moderate at 49 units - enough contrast for legibility, not so much as to fragment the tonal unity. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
