Efim Volkov sits in the centre of the value range, lending the palette a sense of even, sustained light. 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 highest-chroma note - #947A49 - appears at just 7.6%, deployed as a precision accent against the quieter ground. The full value range is 57 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 Efim Volkov's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
