The high-key values of Isaac Levitan give it an effulgent, almost bleached quality. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 8.8%, #7797B1 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. From deepest dark to palest light, the palette traverses 61 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. In the context of Isaac Levitan's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
