John Russell dwells firmly in the shadows, with no more than a whisper of light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #060605 at 52.6% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The highest-chroma note - #462522 - appears at just 4.1%, deployed as a precision accent against the quieter ground. 76 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of John Russell's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
