Robert William Buss occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 8.1%, #6A4D2B carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 62 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 3 sits within the larger chromatic argument that Robert William Buss's complete body of work advances.
