Aleksander Kuprin occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #396957 delivers the chromatic peak at only 8.0% - a small shot of colour with outsized visual impact. Value range is moderate at 54 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Aleksander Kuprin's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
