The value structure of Adolphe Joseph Thomas Monticelli is mid-key: quiet, controlled, and cohesive. 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. The saturated accent, #C3A255, registers at 6.4% - sparse enough to feel like a deliberate surprise. Spanning 50 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. This is palette 6 of Adolphe Joseph Thomas Monticelli's sequence - a single chapter in a chromatic story told across many works.
