George Hyde Pownall sits in the centre of the value range, lending the palette a sense of even, sustained light. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #E88458 functions as the palette's exclamation mark: highest chroma, lowest percentage (6.7%). At 66 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is the light George Hyde Pownall preferred, made measurable.
