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.
