Values in Alexey Bogolyubov rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 6.5% is devoted to #846D41, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 65 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 Alexey Bogolyubov's full range of palettes, group 8 represents one movement in an ongoing chromatic dialogue.
