#0CA4A7 Hex Color

Black text on #0ca4a7 reaches about a 6.9:1 contrast ratio, exceeding WCAG AA's 4.5:1 requirement for normal body text. It works well for buttons, labels, and readable interface copy, while white text needs separate checking.

#0ca4a7 pairs well with charcoal or navy when you need a stable, readable palette, while a muted coral or terracotta accent can add warmth without competing with its cool green-blue base.
