John Hayls is built on dark foundations, with values clustered toward shadow. John Hayls tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. 34.1% of the palette belongs to #19170F, a concentration that makes it the unmistakable visual centre. The saturated accent, #7F6647, registers at 3.4% - sparse enough to feel like a deliberate surprise. A value spread of 63 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This tonal restraint is characteristic of the John Hayls approach: colour serves light, not the reverse. In the context of John Hayls's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
