The value structure of Divisionism is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. #878948 delivers the chromatic peak at only 11.5% - a small shot of colour with outsized visual impact. Value range is moderate at 43 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.
