The color #0D0A91, a deep ultramarine, presents some accessibility challenges. With a low luminance value, it requires careful consideration when used for text or interactive elements. According to WCAG guidelines, sufficient contrast between foreground and background colors is crucial for readability, especially for users with visual impairments. When using #0D0A91 as a background, it is essential to pair it with a very light foreground color to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using online contrast checkers can help verify compliance. Avoid using this color for small text or important icons without sufficient contrast. For links, consider using underlines or other visual cues in addition to color to ensure they are easily identifiable. Also, make sure interactive elements have sufficient focus indicators.
