The value structure of Hildegard of Bingen is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. 31.1% of the palette belongs to #AB8136, a concentration that makes it the unmistakable visual centre. The most saturated colour, #BB5C1B, is reserved to 5.2% of the surface, where it acts as a focal punctuation. At 56 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 6 of Hildegard of Bingen's sequence - a single chapter in a chromatic story told across many works.
