The color #1111A3, a deep shade of ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as text against a white background, it fails to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. This means users with low vision or color deficiencies may struggle to read the text. To improve accessibility, consider using #1111A3 for larger text elements where size can compensate for the lack of contrast, or pair it with a much lighter color like white, yellow, or a very pale blue. Avoid using it for small text or critical interface elements. Also, always ensure sufficient contrast when combining it with other colors, especially in interactive elements like buttons and links. Providing alternative visual cues, such as underlines or icons, alongside color can also enhance accessibility for all users. Testing your color combinations with accessibility checkers is crucial.
