Onyx

#3F3545

A deep, muted onyx — sophisticated balance of hue and saturation that conveys composure and subtle refinement, well-suited to modern, minimalist design.

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.
