Sensible jobs for this swatch

supporting UI accents
text or icons on charcoal / dark mode

Do not use #40bb40 as small body text on white — 2.5:1 misses WCAG AA (4.5:1). Pair it with a darker shade from the scale below, or check pairs in the contrast checker.

Family context: Vitality, optimism, and renewal. Friendly for outdoor and lifestyle brands. Common uses still include buttons, charts, and accents in the Light Green range — always verify the pair for this exact hex in the contrast checker.
