Frank Johnston distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. Only 5.1% is devoted to #6B8957, yet that small allocation delivers the palette's entire chromatic tension. Spanning 35 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. In the context of Frank Johnston's full range of palettes, group 6 represents one movement in an ongoing chromatic dialogue.
