John Brett distributes its values across the middle register, creating harmony without high contrast. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #6A491E delivers the chromatic peak at only 7.0% - a small shot of colour with outsized visual impact. A value spread of 68 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of John Brett's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
