Caspar David Friedrich keeps values measured and balanced, a hallmark of tonal restraint. Temperature is cool-dominant, with blue and green families claiming the largest areas. Mid-saturation across the board: the palette has colour character without chromatic excess. The most saturated colour, #6F4D29, is reserved to 8.6% of the surface, where it acts as a focal punctuation. Spanning 49 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 4 sits within the larger chromatic argument that Caspar David Friedrich's complete body of work advances.
