Nicholas Roerich occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #6B5A34, registers at 9.4% - sparse enough to feel like a deliberate surprise. The value range spans 55 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Nicholas Roerich's palette 18 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
