Igor Grabar is high-key - luminous, open, and weighted toward light. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #D1D0CA at 32.9% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. At 3.0%, #694F38 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 62 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Igor Grabar's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
