#66DD00 Hex Color

Use #66dd00 sparingly as a 10% accent color for interactive elements like call-to-action buttons rather than large background areas. Its extreme brightness can cause eye strain when used in large blocks, but it creates high-impact navigation elements when paired against charcoal.

This color is too light to be used as primary text against a white background, failing standard contrast ratios significantly. It performs best as a vibrant graphic accent or icon color, provided you use dark backgrounds to maintain the necessary 11.9:1 contrast ratio for readability.
