The hex color #1B11A3, Ultramarine, presents several accessibility challenges for web developers. Its dark hue means it requires careful consideration when choosing text and background color combinations. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, especially for users with visual impairments. A color like Ultramarine needs a very light foreground color to meet the contrast ratios specified in WCAG 2.1. Failing to provide adequate contrast can exclude users, making content difficult or impossible to read. It's recommended to use contrast checking tools to ensure compliance. When using this color, prioritize accessibility by testing with diverse user groups and assistive technologies.
