Arnold Böcklin occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. #A99567 functions as the palette's exclamation mark: highest chroma, lowest percentage (10.8%). The full value range is 71 units: broad enough to build convincing three-dimensional form. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Arnold Böcklin's palette 2 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
