Values in Rudolf Koller rest in the mid-range - neither dramatically lit nor steeped in shadow. Rudolf Koller balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #513824, is reserved to 10.0% of the surface, where it acts as a focal punctuation. The full value range is 62 units: broad enough to build convincing three-dimensional form. Palette 5 sits within the larger chromatic argument that Rudolf Koller's complete body of work advances.
