Values in Achille Zo rest in the mid-range - neither dramatically lit nor steeped in shadow. Achille Zo balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #C7B781, registers at 6.0% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 60 units of the value scale - a span that creates natural depth. This is the light Achille Zo preferred, made measurable.
