Isaac Levitan is high-key - luminous, open, and weighted toward light. 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. #D9E8DC at 33.5% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. Only 1.8% is devoted to #575C9A, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 65 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 6 sits within the larger chromatic argument that Isaac Levitan's complete body of work advances.
