Nicholas Roerich is strongly light-biased - shadow is suggested rather than declared. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 10.5%, #6C82AB carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. From deepest dark to palest light, the palette traverses 58 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Nicholas Roerich's palette 6 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
