The high-key values of Oswald Achenbach give it an effulgent, almost bleached quality. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 5.1% is devoted to #8A7049, yet that small allocation delivers the palette's entire chromatic tension. The value range spans 78 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 1 sits within the larger chromatic argument that Oswald Achenbach's complete body of work advances.
