色彩心理学

Dark grays and charcoals project authority, formality, and sophisticated restraint. They are the color of graphite, storm clouds, and evening suits, carrying weight without the absolute finality of black. These tones suggest seriousness and expertise tempered by subtle warmth.

Design Usage

Dark gray is the preferred text color over pure black for reducing eye strain on light backgrounds. It serves as the standard dark-mode surface color in Material Design and other major design systems. Pair it with a single vivid accent color for a minimal, high-impact visual hierarchy.
