The hex color #110B29, also known as Black Rock, presents significant accessibility challenges due to its very dark nature. Its low luminance value results in poor contrast against similarly dark backgrounds, making text or graphical elements nearly invisible to users. This is particularly problematic for individuals with visual impairments, such as those with low vision or color blindness. To ensure accessibility, it is crucial to pair #110B29 with significantly lighter colors. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Using online contrast checkers can help verify compliance. Furthermore, avoid using #110B29 for essential interactive elements, such as buttons or links, without adequate visual cues to distinguish them from the background. Consider alternative color combinations or adding visual indicators to improve usability for all users.
