The value structure of Joseph Anton Koch is mid-key: quiet, controlled, and cohesive. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. All colours lean toward grey, building depth through value rather than colour punch. #8A7053 delivers the chromatic peak at only 8.2% - a small shot of colour with outsized visual impact. The full value range is 57 units: broad enough to build convincing three-dimensional form. Palette 5 sits within the larger chromatic argument that Joseph Anton Koch's complete body of work advances.
