Values in Ivan Shishkin rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #90934A, is reserved to 4.7% of the surface, where it acts as a focal punctuation. The full value range is 56 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Ivan Shishkin's full range of palettes, group 21 represents one movement in an ongoing chromatic dialogue.
