Henry Tonks is high-key - luminous, open, and weighted toward light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #E8E4D9 is not a small accent - at 5.6% it qualifies as a major presence and gives the palette its chromatic identity. The palette spans 50 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 Henry Tonks's sequence - a single chapter in a chromatic story told across many works.
