The color #02315B, a deep shade of Prussian Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background, it requires very light text (ideally white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. 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 essential to verify compliance. Avoid pairing this color with mid-tone shades, as the resulting low contrast will hinder readability, especially for users with visual impairments. When used for interactive elements, such as buttons or links, proper visual cues, like hover effects and sufficient size, are necessary to ensure usability. Thoughtful design choices can mitigate accessibility issues and ensure an inclusive user experience.
