Common sigils draw from five foundational ink palettes. Uncommon pieces introduce spectral colour and higher symmetry orders. Rare sigils. Obsidian, Ember, Glacial, Aurora, Ivory & Gold, carry accent colour highlights visible in the line work. Legendary sigils (Vantablack, Solar Flare, Celestial, Void Opal) are fewer than 6% of supply and include iridescent rendering, celestial glow layers, and perfect 12-fold symmetry. Every trait is deterministic, frozen at mint, and verifiable directly from the contract.
