Rudolf Otto von Ottenfeld distributes its values across the middle register, creating harmony without high contrast. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #76513D functions as the palette's exclamation mark: highest chroma, lowest percentage (2.6%). From deepest dark to palest light, the palette traverses 71 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. In the context of Rudolf Otto von Ottenfeld's full range of palettes, group 3 represents one movement in an ongoing chromatic dialogue.
