Antoine-Jean Gros distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #A3562B, registers at 5.0% - sparse enough to feel like a deliberate surprise. Value range is moderate at 51 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. Antoine-Jean Gros's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
