Expressionism occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. 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. The most saturated colour, #8A7049, is reserved to 11.0% of the surface, where it acts as a focal punctuation. 59 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
