The value structure of Rudolf Otto von Ottenfeld is mid-key: quiet, controlled, and cohesive. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. At 8.8%, #E1D8C9 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 69 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 4 sits within the larger chromatic argument that Rudolf Otto von Ottenfeld's complete body of work advances.
