Alexey Bogolyubov is high-key - luminous, open, and weighted toward light. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #A39167 - appears at just 2.4%, deployed as a precision accent against the quieter ground. At 63 units of value range, the palette has the tonal breadth to sustain complex spatial readings. 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 1 represents one movement in an ongoing chromatic dialogue.
