Paul Jacoulet is high-key - luminous, open, and weighted toward light. Paul Jacoulet balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. All colours lean toward grey, building depth through value rather than colour punch. A single dominant - #F1E6DC at 28.9% - sets the character of the whole composition. The highest-chroma note - #DA5726 - appears at just 1.5%, deployed as a precision accent against the quieter ground. The value range spans 76 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. In the context of Paul Jacoulet's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
