Closer to a slime green than a leafy one, #4ed33d is loud, saturated, and glowing. That brightness makes it a natural accent color for buttons, badges, and eco or gardening branding, though it overwhelms as a full background. Ground it with charcoal or deep navy and it reads sharp instead of glaring. Black text on this hex code hits about 10.7:1 contrast, well past WCAG AA for body text.
