Louis Hayet occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warm hues command this palette; Louis Hayet favours the reds, oranges, and yellows of firelight and earth. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #81766D claims 29.8% of the surface, functioning as the work's tonal foundation. The saturated accent, #B58E55, registers at 5.5% - sparse enough to feel like a deliberate surprise. The palette spans 28 value units: a measured range that delivers coherence over drama. Louis Hayet's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
