Mid-key values give Plautilla Nelli its characteristic quietness - nothing blazes, nothing disappears. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #5D3421 - appears at just 9.7%, deployed as a precision accent against the quieter ground. The value range of 54 units sits in the comfortable middle: enough depth, enough light, neither extreme. The palette is a signature: Plautilla Nelli's particular sense of value, warmth, and colour weight made legible.
