Andreas Achenbach occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. Only 4.0% is devoted to #D7A65B, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 57 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is the light Andreas Achenbach preferred, made measurable.
