The hex color #151704, also known as Green Waterloo, presents significant accessibility challenges due to its very low luminance. Its contrast ratio against a white background is critically low, failing all WCAG (Web Content Accessibility Guidelines) success criteria for contrast. This means that text or interactive elements using this color on a white background (or any significantly lighter color) would be very difficult, if not impossible, for users with visual impairments to perceive. Similarly, using white text on a background of #151704 would pose the same problems. To improve accessibility, this color should only be used in conjunction with much lighter colors or as a decorative element where it is not essential for conveying information or functionality. Careful consideration and testing with accessibility tools are essential to ensure that all users can effectively interact with content utilizing this color.
