Carl Gustav Carus distributes its values across the middle register, creating harmony without high contrast. Carl Gustav Carus keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #4C3F33, registers at 7.0% - sparse enough to feel like a deliberate surprise. The full value range is 81 units: broad enough to build convincing three-dimensional form. In the context of Carl Gustav Carus's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
