Giovanni Costa distributes its values across the middle register, creating harmony without high contrast. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 11.4%, #CABA98 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 52 units across the value scale, the palette keeps contrast readable without letting it dominate. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 5 sits within the larger chromatic argument that Giovanni Costa's complete body of work advances.
