Mid-key values give John William Waterhouse its characteristic quietness - nothing blazes, nothing disappears. John William Waterhouse orchestrates warmth above all else - reds, ambers, and siennas take the lead. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #F3F2F2 claims 25.3% of the surface, functioning as the work's tonal foundation. The saturated accent, #331D22, registers at 6.3% - sparse enough to feel like a deliberate surprise. The full value range is 70 units: broad enough to build convincing three-dimensional form. Palette 4 sits within the larger chromatic argument that John William Waterhouse's complete body of work advances.
