Enrico Nardi sits in the centre of the value range, lending the palette a sense of even, sustained light. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #C9DEF1 delivers the chromatic peak at only 4.4% - a small shot of colour with outsized visual impact. From deepest dark to palest light, the palette traverses 65 units of the value scale - a span that creates natural depth. Palette 4 sits within the larger chromatic argument that Enrico Nardi's complete body of work advances.
