Elisabeth Sonrel occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. #7A5131 delivers the chromatic peak at only 4.2% - a small shot of colour with outsized visual impact. From deepest dark to palest light, the palette traverses 61 units of the value scale - a span that creates natural depth. 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 Elisabeth Sonrel's complete body of work advances.
