Joseph Rebell occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #CCC690, is reserved to 5.6% of the surface, where it acts as a focal punctuation. The palette spans 53 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. This is palette 1 of Joseph Rebell's sequence - a single chapter in a chromatic story told across many works.
