Realism works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Built 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. #736D3D delivers the chromatic peak at only 3.9% - a small shot of colour with outsized visual impact. At 58 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
