The value structure of Rosalba Carriera is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 5.7% is devoted to #0E292B, yet that small allocation delivers the palette's entire chromatic tension. At 80 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is palette 5 of Rosalba Carriera's sequence - a single chapter in a chromatic story told across many works.
