The high-key values of Karl Wilhelm Diefenbach give it an effulgent, almost bleached quality. Temperature is cool-dominant, with blue and green families claiming the largest areas. All colours lean toward grey, building depth through value rather than colour punch. A single dominant - #FFFFFF at 61.0% - sets the character of the whole composition. #147F93 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.1%). At 82 units of value range, the palette has the tonal breadth to sustain complex spatial readings. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 2 of Karl Wilhelm Diefenbach's sequence - a single chapter in a chromatic story told across many works.
