#C9FF00 Hex Color

Because #c9ff00 commands so much attention, use it sparingly as a functional accent color rather than a main background. It is highly effective for call-to-action buttons or UI highlights that need to pop against dark or neutral backgrounds like charcoal.

This electric neon lime creates a striking contrast against deep, neutral tones that ground its intensity. Try pairing #c9ff00 with charcoal or matte black to prevent visual fatigue, or use it alongside dark navy to create a sophisticated yet modern high-contrast aesthetic.
