Psychology
Gray is the connective tissue of interface design — neutral, balanced, and quiet. It supports without competing.
Meaning
Sophistication, neutrality, and restraint. Warm grays feel inviting; cool grays feel modern and technical.
Applications
Essential for backgrounds, borders, dividers, and secondary text in product UIs. Build a 9–11 step gray ramp early in any design system.
