Frank Johnston is strongly light-biased - shadow is suggested rather than declared. Temperature is cool-dominant, with blue and green families claiming the largest areas. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. #D3B754 is not a small accent - at 20.1% it qualifies as a major presence and gives the palette its chromatic identity. At 55 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 1 of Frank Johnston's sequence - a single chapter in a chromatic story told across many works.
