The value structure of Caspar David Friedrich is mid-key: quiet, controlled, and cohesive. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #D7B46B, is reserved to 4.7% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 62 units of the value scale - a span that creates natural depth. The palette is recognisably Caspar David Friedrich's own: particular in its temperature, chroma, and the economy of its brightest note.
