August von Pettenkofen is high in key: pale, luminous, and filled with optical air. August von Pettenkofen builds on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #AE8E60 delivers the chromatic peak at only 8.8% - a small shot of colour with outsized visual impact. From deepest dark to palest light, the palette traverses 64 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. Palette 3 sits within the larger chromatic argument that August von Pettenkofen's complete body of work advances.
