cloudscape is high in key: pale, luminous, and filled with optical air. 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. #543D1E delivers the chromatic peak at only 4.1% - a small shot of colour with outsized visual impact. At 56 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
