Arshile Gorky is high-key - luminous, open, and weighted toward light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #C29D48 delivers the chromatic peak at only 5.2% - a small shot of colour with outsized visual impact. At 59 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 Arshile Gorky's sequence - a single chapter in a chromatic story told across many works.
