The color #110FA4, a deep ultramarine, presents significant accessibility challenges, especially concerning color contrast. When used as text, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Therefore, pairing it with colors like white (#FFFFFF) or very light grays is crucial. Avoid using it with dark backgrounds or colors of similar luminance, as this can cause eye strain and make content illegible for users with visual impairments. When used for graphical elements or UI components, ensure sufficient contrast with adjacent elements to help users easily distinguish interactive parts of the interface. Consider adding alternative text descriptions for images using this color to provide context for users who cannot perceive it visually.
