Harry Phelan Gibb distributes its values across the middle register, creating harmony without high contrast. Harry Phelan Gibb builds on cool foundations: the palette favours the blue-cyan-green arc. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #B9A56E delivers the chromatic peak at only 8.5% - a small shot of colour with outsized visual impact. Value range is moderate at 39 units - enough contrast for legibility, not so much as to fragment the tonal unity. 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 Harry Phelan Gibb's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
