Mid-key values give William Daniell its characteristic quietness - nothing blazes, nothing disappears. William Daniell builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #CC6726, registers at 2.0% - sparse enough to feel like a deliberate surprise. The value range spans 60 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. These proportions encode William Daniell's instinctive sense of how much of each quality the eye can hold.
