The hex color #181E80, also known as Deep Koamaru, presents some accessibility challenges, particularly regarding color contrast. When used as a background color, it requires very light text to ensure readability, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This dark shade of blue may cause difficulty for users with visual impairments if paired with mid-tone or dark colors. Therefore, it's crucial to use color contrast checkers to validate the chosen color combinations. Consider using white or very light shades of yellow or green for text to maximize legibility. When used for interactive elements, such as buttons or links, sufficient contrast is even more critical to ensure usability for all users. Always provide alternative visual cues, like underlines or icons, to enhance accessibility for colorblind users.
