The value structure of Octav Bancila 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 highest-chroma note - #5A3A36 - appears at just 5.7%, deployed as a precision accent against the quieter ground. At 49 units across the value scale, the palette keeps contrast readable without letting it dominate. Palette 4 sits within the larger chromatic argument that Octav Bancila's complete body of work advances.
