Nicholas Roerich occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. At 9.8%, #7A9AD0 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The value range of 53 units sits in the comfortable middle: enough depth, enough light, neither extreme. 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 17 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
