Cobalt

#01388B

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

Psychology

Blue is the world's most-preferred color across age, gender, and culture. It lowers heart rate, conveys stability and trust, and reads as professional almost regardless of context.

Meaning

Trust, authority, and depth — which is why it anchors finance, healthcare, government, and big-tech logos. Lighter blues feel airy and aspirational; navy and midnight feel established.

Applications

Foundational for SaaS, fintech, and enterprise interfaces. Mix with warm accents to avoid the corporate-blue trap of looking like every competitor.
