#4EC40F Hex Color
Loud, lush, and hard to miss
#4ec40f is a loud, neon-leaning green with a warm yellow undertone. That saturation makes it a strong small accent for calls to action, eco branding, and highlights, though it overwhelms as a full background. Black text reads clearly on it at about 9.2:1 contrast, so buttons and badges stay accessible. Pair it with deep navy for balance.
