Paul Signac is high in key: pale, luminous, and filled with optical air. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. #BE7022 delivers the chromatic peak at only 4.3% - a small shot of colour with outsized visual impact. The palette spans 53 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 4 sits within the larger chromatic argument that Paul Signac's complete body of work advances.
