The color #0B0FA9, a deep ultramarine, presents some accessibility challenges, especially in text-based applications. Its low luminance value means it requires careful pairing with lighter colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #0B0FA9 for text, it's crucial to test the contrast against the background color using online tools or accessibility checkers. For backgrounds, consider using very light shades of yellow, white, or even light gray to maximize readability. Avoid pairing it with other dark colors, as this will result in insufficient contrast. In user interface design, ensure that interactive elements using this color, such as buttons or links, have clear visual cues and sufficient contrast to be easily identifiable by users with visual impairments. A good strategy is to use a lighter border or text shadow to enhance the element's prominence.
