Boris Kustodiev occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 7.0%, #87544B 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 55 units of the value scale - a span that creates natural depth. In the context of Boris Kustodiev's full range of palettes, group 9 represents one movement in an ongoing chromatic dialogue.
