Fyodor Vasilyev is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. #C9E8D2 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.4%). At 66 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Fyodor Vasilyev's complete body of work advances.
