Arthur Rackham keeps values measured and balanced, a hallmark of tonal restraint. Warm and cool tones are held in careful balance - neither family dominates, creating tension and resolution simultaneously. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The saturated accent, #9D8167, registers at 8.4% - sparse enough to feel like a deliberate surprise. The full value range is 57 units: broad enough to build convincing three-dimensional form. Arthur Rackham's palette 12 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
