Curated color palette

Blue Color Palette

A blue palette moving from a near-white cool surface through a saturated action blue to a deep navy.

Check the exact foreground/background pair instead of assuming every blue works with white text.

Palette colors

Background Ice #EAF4FF
Soft accent Sky #BDE0FE
Secondary accent Steel #5FA8D3
Primary action Royal #2563EB
Text / dark surface Deep Navy #0B1F3A

Each swatch chooses black or white label text using the higher WCAG contrast ratio for that single solid color. Final component contrast still depends on your actual text size and context.

Suggested use

Suitable for product UI, charts, editorial graphics, and visual systems that need a broad cool range from subtle surfaces to strong actions.
