Alessandro Grevenbroeck occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Alessandro Grevenbroeck tilts toward cool - blues and silver-greys carry the structural weight. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #826847, registers at 7.1% - sparse enough to feel like a deliberate surprise. At 43 units across the value scale, the palette keeps contrast readable without letting it dominate. 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 Alessandro Grevenbroeck's complete body of work advances.
