Valentin Serov is low-key throughout, a quality associated with Nocturnal Sienna - deep shadows dominate the composition. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 1.8%, #C7A37D carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 53 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. This is palette 14 of Valentin Serov's sequence - a single chapter in a chromatic story told across many works.
