Values in Hildegard of Bingen rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Mid-saturation across the board: the palette has colour character without chromatic excess. The most saturated colour, #CC802C, is reserved to 10.0% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 60 units of the value scale - a span that creates natural depth. 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 4 of Hildegard of Bingen's sequence - a single chapter in a chromatic story told across many works.
