Impressionism 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. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #9D8539, registers at 4.4% - sparse enough to feel like a deliberate surprise. The palette spans 54 value units: a measured range that delivers coherence over drama. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
