Values in Arnold Böcklin 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. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. 25.6% of the palette belongs to #322F1B, a concentration that makes it the unmistakable visual centre. At 3.5%, #C09E6B carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 64 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 5 of Arnold Böcklin's sequence - a single chapter in a chromatic story told across many works.
