Robert Harris works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 28.6%, #C2D1E0 functions less as a colour accent and more as a complete atmospheric environment. #1E2F39 delivers the chromatic peak at only 2.6% - a small shot of colour with outsized visual impact. The full value range is 67 units: broad enough to build convincing three-dimensional form. 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 Robert Harris's full range of palettes, group 1 represents one movement in an ongoing chromatic dialogue.
