The color #0F1B8C, a deep ultramarine, presents some accessibility challenges, especially when used as a text color. Its low luminance value means that it requires careful consideration of contrast ratios. When used as a background, it's imperative to pair it with a light-colored text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text, and 3:1 for larger text, as per WCAG guidelines. Using online contrast checkers can help verify compliance. Avoid using this color for crucial UI elements or informative text without ensuring sufficient contrast. Visually impaired users may struggle to distinguish elements if the contrast is inadequate. For decorative purposes, these rules are less stringent, but prioritizing accessibility ensures a more inclusive user experience. When using it for links, ensure there's sufficient contrast to distinguish them from the surrounding text.
