Igor Grabar is high in key: pale, luminous, and filled with optical air. Igor Grabar builds on cool foundations: the palette favours the blue-cyan-green arc. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #DBDEDC at 31.6% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. #89744B functions as the palette's exclamation mark: highest chroma, lowest percentage (2.4%). A value spread of 68 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 2 of Igor Grabar's sequence - a single chapter in a chromatic story told across many works.
