Mid-key values give Oswald Achenbach its characteristic quietness - nothing blazes, nothing disappears. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #674323, is reserved to 3.9% of the surface, where it acts as a focal punctuation. A value spread of 59 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. This is palette 5 of Oswald Achenbach's sequence - a single chapter in a chromatic story told across many works.
