#00FF66 Hex Color

Use #00ff66 primarily as an intentional accent color for small elements like buttons, toggle switches, or notification badges. Because this neon green is so visually intense, pairing it with dark charcoal or deep black backgrounds helps anchor the color and ensures the rest of your interface remains usable.

While #00ff66 is highly visible, it typically fails standard WCAG contrast ratios when used as text against white backgrounds. To keep your designs accessible, reserve this neon green for non-text graphic elements or use it as a striking background color for bold black text.
