A loud, saturated green with a cool, slightly blue undertone. #1bb366 works best as an accent or call-to-action color, where its intensity draws the eye without taking over a layout. Use it sparingly next to deep plum or charcoal, since at full coverage it can overwhelm. Black text sits comfortably on it, with contrast near 7.7:1, enough for WCAG AA body copy.
