The value structure of Gerrit Dou is mid-key: quiet, controlled, and cohesive. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. A single dominant - #1D1917 at 34.3% - sets the character of the whole composition. The saturated accent, #643B1F, registers at 4.8% - sparse enough to feel like a deliberate surprise. At 70 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette is a signature: Gerrit Dou's particular sense of value, warmth, and colour weight made legible.
