William Williams sits in the centre of the value range, lending the palette a sense of even, sustained light. William Williams tilts toward cool - blues and silver-greys carry the structural weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #BA742D - appears at just 2.2%, deployed as a precision accent against the quieter ground. The full value range is 63 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 5 of William Williams's sequence - a single chapter in a chromatic story told across many works.
