John Varley sits in the centre of the value range, lending the palette a sense of even, sustained light. Temperature is cool-dominant, with blue and green families claiming the largest areas. Mid-range chroma keeps the palette grounded - colourful but not strident. #4F311C functions as the palette's exclamation mark: highest chroma, lowest percentage (5.6%). At 67 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 4 of John Varley's sequence - a single chapter in a chromatic story told across many works.
