Anna Ostroumova-Lebedeva works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. A single dominant - #FAF4E8 at 39.2% - sets the character of the whole composition. #D2CEC6 at 3.5% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. At 73 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 3 of Anna Ostroumova-Lebedeva's sequence - a single chapter in a chromatic story told across many works.
