David Johnson is high-key - luminous, open, and weighted toward light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #E3C383, registers at 3.3% - sparse enough to feel like a deliberate surprise. The full value range is 66 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of David Johnson's sequence - a single chapter in a chromatic story told across many works.
