#43C0DF Hex Color

Black text has about 9.8:1 contrast against #43c0df, comfortably exceeding the WCAG AA 4.5:1 requirement for body text. Use black or very dark text for readable labels and paragraphs; white text provides much weaker contrast.

Pair #43c0df with charcoal or navy when you need structure without losing its airy character. Charcoal creates softer interface contrast, while navy adds weight for headings, buttons, or technology-focused branding.
