Serge Sudeikin is strongly light-biased - shadow is suggested rather than declared. 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. At 31.8%, #FDFED4 functions less as a colour accent and more as a complete atmospheric environment. Rather than a studied accent, #D9D1B7 takes 1.7% - a bold allocation that saturates the composition's atmosphere. A value spread of 56 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of Serge Sudeikin's sequence - a single chapter in a chromatic story told across many works.
