John William Waterhouse distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 1.9% is devoted to #A56A78, yet that small allocation delivers the palette's entire chromatic tension. 52 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of John William Waterhouse's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
