Lime

This vibrant neon should be reserved for high-impact accents or interactive elements like buttons. Because it is extremely saturated, pairing #00ff00 with deep neutrals like charcoal or matte black ensures readability while maintaining a modern, high-contrast aesthetic for your interface.

While #00ff00 provides high visibility, it can be difficult to read if used as a primary text color. Always pair this lime shade with bold, dark text or use it sparingly against a solid black background to meet basic web accessibility standards.
