Mid-key values give Rudolf Otto von Ottenfeld its characteristic quietness - nothing blazes, nothing disappears. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 4.0% is devoted to #8F6940, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 62 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This is the light Rudolf Otto von Ottenfeld preferred, made measurable.
