Ivan Shishkin distributes its values across the middle register, creating harmony without high contrast. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #A4814A, registers at 3.9% - sparse enough to feel like a deliberate surprise. The full value range is 60 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light Ivan Shishkin preferred, made measurable.
