Paul Jacoulet is high in key: pale, luminous, and filled with optical air. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Mid-range chroma keeps the palette grounded - colourful but not strident. Paul Jacoulet gives 25.9% of the composition to a single #FCF3C6 - a decisive chromatic anchor. The highest-chroma note - #EB6B45 - appears at just 4.7%, deployed as a precision accent against the quieter ground. 54 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Paul Jacoulet's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
