Jock Macdonald is strongly light-biased - shadow is suggested rather than declared. Jock Macdonald tilts toward cool - blues and silver-greys carry the structural weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #C9CACF claims 26.6% of the surface, functioning as the work's tonal foundation. Only 4.7% is devoted to #C4A850, yet that small allocation delivers the palette's entire chromatic tension. 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 3 of Jock Macdonald's sequence - a single chapter in a chromatic story told across many works.
