The color #111587, Ultramarine, presents several accessibility considerations for web development. Its dark hue results in low contrast when paired with lighter text or interface elements. To ensure readability and usability, it's crucial to use sufficiently light text colors like white or very light grays on backgrounds of #111587. Adhering to WCAG (Web Content Accessibility Guidelines) contrast ratio requirements is vital; a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended.

Supplement color cues with text labels, icons, or underlines to make the interface accessible to users with color vision deficiencies. Thoroughly testing the color combination with accessibility tools is crucial to ensure inclusivity.
