Robert William Buss occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The most saturated colour, #795F33, is reserved to 11.8% of the surface, where it acts as a focal punctuation. 69 units of value range underpin the palette's structural clarity: the eye always knows where light falls. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Robert William Buss's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
