The value structure of Nicolas Tournier is mid-key: quiet, controlled, and cohesive. Yellow, ochre, sienna: warm hues that Nicolas Tournier deploys as the palette's primary energy. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #27231E claims 30.4% of the surface, functioning as the work's tonal foundation. #8B4122 delivers the chromatic peak at only 2.8% - a small shot of colour with outsized visual impact. At 48 units across the value scale, the palette keeps contrast readable without letting it dominate. Palette 4 sits within the larger chromatic argument that Nicolas Tournier's complete body of work advances.
