John Collier keeps values measured and balanced, a hallmark of tonal restraint. 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. The highest-chroma note - #A4984C - appears at just 6.1%, deployed as a precision accent against the quieter ground. The value range of 46 units sits in the comfortable middle: enough depth, enough light, neither extreme. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of John Collier's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
