Plautilla Nelli occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. 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. Only 7.5% is devoted to #C8AF72, yet that small allocation delivers the palette's entire chromatic tension. The value range of 45 units sits in the comfortable middle: enough depth, enough light, neither extreme. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 1 of Plautilla Nelli's sequence - a single chapter in a chromatic story told across many works.
