Walter Sickert distributes its values across the middle register, creating harmony without high contrast. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 2.1% is devoted to #E4A20D, yet that small allocation delivers the palette's entire chromatic tension. The value range of 52 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light Walter Sickert preferred, made measurable.
