The value structure of Louis Gurlitt is mid-key: quiet, controlled, and cohesive. 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. #302611 functions as the palette's exclamation mark: highest chroma, lowest percentage (8.1%). A value spread of 60 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 4 of Louis Gurlitt's sequence - a single chapter in a chromatic story told across many works.
