The hex color #1E108B, also known as Ultramarine, presents some accessibility challenges. Its dark nature results in a low contrast ratio against standard white backgrounds, potentially making text or interactive elements difficult to read for users with visual impairments. To improve accessibility, consider pairing Ultramarine with lighter colors such as white (#FFFFFF), light yellow (#FFFFE0) or very light grays. These combinations offer better contrast, adhering to WCAG (Web Content Accessibility Guidelines) standards for readability. Developers should also test color combinations using accessibility tools to ensure sufficient contrast ratios for users with different visual needs. Remember to avoid using this color for important information without high contrast.
