Oswald Achenbach occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 5.8% is devoted to #CAB07C, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 64 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Taken together, these qualities constitute Oswald Achenbach's chromatic voice - distinctive enough to be read across an entire body of work.
