The color #1108AC, a deep shade of ultramarine, presents several accessibility considerations for web developers. Its low lightness value (approximately 6%) means that it inherently lacks sufficient contrast against standard white backgrounds. This poses readability issues for users, especially those with visual impairments. To ensure accessibility, it is imperative to pair this color with very light text colors such as white or a light yellow to meet WCAG (Web Content Accessibility Guidelines) contrast ratio requirements, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using this color for crucial interactive elements without proper visual cues, as users might not be able to discern the boundaries or affordances. Providing alternative visual indicators, such as borders or icons, can greatly enhance the usability and inclusivity of designs incorporating #1108AC.
