The value structure of Joan Blaeu is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. At 2.3%, #71403F carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 41 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 3 sits within the larger chromatic argument that Joan Blaeu's complete body of work advances.
