John Duncan Fergusson keeps values measured and balanced, a hallmark of tonal restraint. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #DCB069 functions as the palette's exclamation mark: highest chroma, lowest percentage (2.0%). 62 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of John Duncan Fergusson's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
