Low-key values are the structural spine of Friedrich Wilhelm Christoph Morgenstern, giving it gravity and atmosphere. 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 - #A13B10 - appears at just 1.6%, deployed as a precision accent against the quieter ground. At 57 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. This is the light Friedrich Wilhelm Christoph Morgenstern preferred, made measurable.
