Using this color
#DDFF57 (#ddff57) sits in the lime family at about 72° hue, 100% saturation, and 67% lightness. Contrast is 1.13:1 on white and 18.52:1 on black, so near-black labels read more clearly on the swatch itself. Nearest Tailwind token: lime-300 (approximation unless the hex is an official scale stop).
Sensible jobs for this swatch
Do not use #ddff57 as small body text on white — 1.13:1 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: Energy, youth, and experimentation. High-visibility accents and playful UIs. Common uses still include buttons, charts, and accents in the Lime range — always verify the pair for this exact hex in the contrast checker.
