Placido Costanzi keeps values measured and balanced, a hallmark of tonal restraint. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. At 7.9%, #5A3721 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. Value range is moderate at 48 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Placido Costanzi's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
