The value structure of Rudolf Otto von Ottenfeld is mid-key: quiet, controlled, and cohesive. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #918155 delivers the chromatic peak at only 8.9% - a small shot of colour with outsized visual impact. The full value range is 59 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 2 of Rudolf Otto von Ottenfeld's sequence - a single chapter in a chromatic story told across many works.
