Lime
A high-intensity neon green statement
Lime #00ff00 is a high-intensity, neon shade that demands immediate attention. Due to its extreme saturation, it works best as a sharp accent rather than a full background. Black text provides excellent readability against this hex code, aiding accessibility in UI design. If you need other shades of green to balance your palette, pair this bright tone with dark neutrals to ground its visual energy.
