The value structure of Robert Zund is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #556828 - appears at just 4.0%, deployed as a precision accent against the quieter ground. Spanning 54 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. These proportions encode Robert Zund's instinctive sense of how much of each quality the eye can hold.
