The value structure of Hildegard of Bingen is mid-key: quiet, controlled, and cohesive. Temperature is balanced: the palette pits warm earth against cool sky without declaring a winner. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The saturated accent, #C7AF6D, registers at 6.9% - sparse enough to feel like a deliberate surprise. The palette spans 47 value units: a measured range that delivers coherence over drama. This is palette 3 of Hildegard of Bingen's sequence - a single chapter in a chromatic story told across many works.
