The hex color #0A2B47, also known as Blue Whale, presents some accessibility challenges due to its dark nature. When used as a background color, it requires very light text (white or near-white) to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using a color contrast checker is crucial to verify compliance. For users with visual impairments, especially those with low vision, inadequate contrast can make text difficult or impossible to read. Additionally, avoid using this color for essential UI elements without careful consideration of contrast, as it could hinder usability. Proper testing with diverse user groups is always recommended to ensure inclusivity.
