#FCB900 Hex Color

Black text is the clear choice, with about 12.1:1 contrast, well above the WCAG AA requirement of 4.5:1. White text fails at roughly 1.7:1, so keep any type dark when it sits on this yellow.

Deep navy and dark plum balance its intensity best, while charcoal keeps things grounded in UI work. For a warmer scheme, use amber and burnt orange neighbors rather than pure red, which clashes.
