The color #11108b, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue results in a low luminance value, which means it requires careful pairing with contrasting colors to ensure readability. When used as a background, it necessitates light-colored text (white or very light shades) to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Specifically, aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Using contrast checking tools is crucial to verify compliance. Avoid using #11108b for essential interactive elements without sufficient contrast, as this can severely hinder usability for users with visual impairments. Furthermore, consider providing alternative styling options for users who need to customize their viewing experience.
