Andreas Achenbach occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. #D9C67C delivers the chromatic peak at only 10.1% - a small shot of colour with outsized visual impact. A value spread of 62 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Andreas Achenbach's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
