Not a soft sage or muted forest tone, bright green demands attention. #39cc39 is highly saturated and light, so it reads almost neon on screen and works best in small doses: buttons, highlights, eco and pharmacy accents. As a full background it can fatigue the eye. Pair it with charcoal or plum rather than white, and know that black text clears AA on it at roughly 9.9:1 contrast.
