The value structure of Johannes Vermeer is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #B99A62, registers at 3.1% - sparse enough to feel like a deliberate surprise. A value spread of 61 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Johannes Vermeer's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
