The value structure of Josef Carl Berthold Puttner is mid-key: quiet, controlled, and cohesive. 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. The highest-chroma note - #453727 - appears at just 6.6%, deployed as a precision accent against the quieter ground. Value range is moderate at 46 units - enough contrast for legibility, not so much as to fragment the tonal unity. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that Josef Carl Berthold Puttner's complete body of work advances.
