Raoul Dufy is strongly light-biased - shadow is suggested rather than declared. Raoul Dufy tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #A84C29, registers at 2.2% - sparse enough to feel like a deliberate surprise. A value spread of 63 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. In the context of Raoul Dufy's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
