Marietta Robusti distributes its values across the middle register, creating harmony without high contrast. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #622D37 functions as the palette's exclamation mark: highest chroma, lowest percentage (5.6%). The full value range is 63 units: broad enough to build convincing three-dimensional form. Marietta Robusti's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
