Values in August von Rentzell rest in the mid-range - neither dramatically lit nor steeped in shadow. 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. #9D865C functions as the palette's exclamation mark: highest chroma, lowest percentage (10.0%). The value range of 45 units sits in the comfortable middle: enough depth, enough light, neither extreme. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. The palette is recognisably August von Rentzell's own: particular in its temperature, chroma, and the economy of its brightest note.
