The color #0F11A4, also known as Ultramarine, presents some accessibility challenges, especially in web design. Its dark hue means that text displayed in this color requires a light background to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using Ultramarine, careful consideration must be given to the background color to meet these standards. Tools like contrast checkers can be invaluable in determining appropriate color pairings. Moreover, avoid using this color for essential visual cues or links without additional indicators, as users with color vision deficiencies may struggle to distinguish them. Providing alternative cues, such as underlines or icons, can enhance accessibility for a wider audience.
