Mid-key values give Prospero Piatti its characteristic quietness - nothing blazes, nothing disappears. Warm hues command this palette; Prospero Piatti favours the reds, oranges, and yellows of firelight and earth. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #EADEBD, covers 5.0% of the surface: too much to call an accent, too strong to ignore. From deepest dark to palest light, the palette traverses 69 units of the value scale - a span that creates natural depth. These proportions encode Prospero Piatti's instinctive sense of how much of each quality the eye can hold.
