The value structure of Nikolay Bogdanov-Belsky is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #BBAC50, registers at 5.2% - sparse enough to feel like a deliberate surprise. The palette spans 54 value units: a measured range that delivers coherence over drama. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 12 of Nikolay Bogdanov-Belsky's sequence - a single chapter in a chromatic story told across many works.
