François Barraud is strongly light-biased - shadow is suggested rather than declared. François Barraud tilts toward cool - blues and silver-greys carry the structural weight. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. #5C1508 functions as the palette's exclamation mark: highest chroma, lowest percentage (0.5%). 67 units of value range underpin the palette's structural clarity: the eye always knows where light falls. 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 François Barraud's complete body of work advances.
