The value structure of Louis Gurlitt is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #AB8665 - appears at just 5.0%, deployed as a precision accent against the quieter ground. Value range is moderate at 54 units - enough contrast for legibility, not so much as to fragment the tonal unity. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is the light Louis Gurlitt preferred, made measurable.
