Andreas Achenbach occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #634A2F - appears at just 3.6%, deployed as a precision accent against the quieter ground. Value range is moderate at 51 units - enough contrast for legibility, not so much as to fragment the tonal unity. This is palette 13 of Andreas Achenbach's sequence - a single chapter in a chromatic story told across many works.
