Chartreuse

This intense shade balances best against dark, neutral tones that can contain its brightness. Pairing #7fff00 with charcoal or deep navy creates a sophisticated, high-contrast look that prevents the neon green from feeling too chaotic or overwhelming in a design.

Chartreuse is extremely bright and often fails accessibility standards for readability when used as a primary text color against white. Always use it as a vivid graphic accent, or layer it over solid black for the highest possible contrast ratio.
