Louis Comfort Tiffany is low-key throughout, a quality associated with Tenebrous Bister - deep shadows dominate the composition. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. At 42.5%, #0F0A08 functions less as a colour accent and more as a complete atmospheric environment. Only 2.5% is devoted to #C46B2E, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 77 units: broad enough to build convincing three-dimensional form. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Louis Comfort Tiffany's full range of palettes, group 9 represents one movement in an ongoing chromatic dialogue.
