Andreas Achenbach works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Andreas Achenbach builds on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. Only 9.7% is devoted to #E4D8B7, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 69 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 palette 1 of Andreas Achenbach's sequence - a single chapter in a chromatic story told across many works.
