August von Rentzell sits in the centre of the value range, lending the palette a sense of even, sustained light. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #673C24, is reserved to 4.0% of the surface, where it acts as a focal punctuation. The palette spans 44 value units: a measured range that delivers coherence over drama. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 1 sits within the larger chromatic argument that August von Rentzell's complete body of work advances.
