The color #063E61, also known as Astronaut Blue, presents several accessibility considerations for web development. Its dark hue results in a low contrast ratio when paired with similarly dark colors, making text and user interface elements difficult to read for users with visual impairments. To ensure accessibility, it's crucial to use this color with light backgrounds, such as white or light gray, to achieve a contrast ratio that meets 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. Additionally, avoid using #063E61 as the sole indicator for interactive elements, as colorblind users might not be able to distinguish them. Supplement color cues with text labels or icons to enhance usability for all users, making the web experience more inclusive.
