Jules-Alexandre Grun occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #C1AB87, registers at 4.0% - sparse enough to feel like a deliberate surprise. The full value range is 64 units: broad enough to build convincing three-dimensional form. In the context of Jules-Alexandre Grun's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
