Sergey Solomko is strongly light-biased - shadow is suggested rather than declared. Warmth dominates - the palette of Sergey Solomko leans heavily on the yellow-orange-red arc of the colour wheel. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The highest-chroma note - #764B48 - appears at just 4.0%, deployed as a precision accent against the quieter ground. The full value range is 62 units: broad enough to build convincing three-dimensional form. Palette 4 sits within the larger chromatic argument that Sergey Solomko's complete body of work advances.
