Mid-key values give Louis Comfort Tiffany its characteristic quietness - nothing blazes, nothing disappears. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #171210 at 28.3% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. The saturated accent, #E0C888, registers at 4.5% - sparse enough to feel like a deliberate surprise. The value range spans 73 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Palette 4 sits within the larger chromatic argument that Louis Comfort Tiffany's complete body of work advances.
