David Allan distributes its values across the middle register, creating harmony without high contrast. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. #624E13 delivers the chromatic peak at only 9.8% - a small shot of colour with outsized visual impact. The value range spans 77 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. In the context of David Allan's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
