The value structure of Domenico Ghirlandaio is mid-key: quiet, controlled, and cohesive. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Mid-saturation across the board: the palette has colour character without chromatic excess. The highest-chroma note - #C08922 - appears at just 9.1%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 58 units of the value scale - a span that creates natural depth. Together these qualities point to the open-air Impressionist method: recording light rather than local colour. Domenico Ghirlandaio's palette 12 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
