Nicholas Roerich is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #B6A6C6, is reserved to 10.5% of the surface, where it acts as a focal punctuation. At 55 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. Palette 7 sits within the larger chromatic argument that Nicholas Roerich's complete body of work advances.
