Wilhelm Karl Rauber sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The saturated accent, #787246, registers at 4.2% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 55 units of the value scale - a span that creates natural depth. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 2 of Wilhelm Karl Rauber's sequence - a single chapter in a chromatic story told across many works.
