The hex color #0B2F51, also known as Blue Whale, presents some accessibility challenges, primarily due to its low lightness value. When used as a background color, it requires very light text 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 that the chosen text color meets these standards. Failure to provide adequate contrast can significantly hinder the experience for users with visual impairments, including those with low vision or color blindness. It's also important to consider users browsing in bright environments where screen glare can further reduce perceived contrast. Therefore, careful selection of foreground text color and thorough testing are essential for ensuring accessibility.
