Values in Willi Baumeister rest in the mid-range - neither dramatically lit nor steeped in shadow. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. #2C2B32 claims 33.8% of the surface, functioning as the work's tonal foundation. #DCD7BB functions as the palette's exclamation mark: highest chroma, lowest percentage (1.1%). 59 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 4 sits within the larger chromatic argument that Willi Baumeister's complete body of work advances.
