The color #120D8F, a deep shade of ultramarine, presents significant accessibility challenges, particularly in web design. Its low luminance value necessitates careful consideration of contrast ratios. When used as a background color, it requires very light text (white or near-white) to ensure readability and compliance with WCAG guidelines. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using color contrast analyzers is crucial to verify sufficient contrast. Avoid pairing this color with other dark hues, as this will render content illegible for users with low vision or color blindness. It's also essential to provide alternative visual cues, such as underlines or icons, for links and interactive elements, as relying solely on color differences may exclude certain users. Thoughtful application and thorough testing are essential to ensure an inclusive user experience.
