The value structure of Analytical Cubism is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. Only 9.1% is devoted to #91723F, yet that small allocation delivers the palette's entire chromatic tension. The value range of 52 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.
