#66FC00 Hex Color

Treat #66fc00 as a high-impact accent color rather than a main background, as its extreme intensity can easily overwhelm the viewer. It pairs effectively with charcoal or deep black text to ensure high readability for buttons or call-to-action elements.

Its extreme brightness comes from high saturation combined with strong yellow undertones, which push it closer to fluorescent limits. Because of this high energy, it naturally draws the eye, making it suitable for functional alerts or specific interface highlights.
