The hex color #11088e, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, the contrast ratio is quite low, making it difficult for users with visual impairments to read. It is crucial to ensure a sufficient contrast ratio, ideally meeting WCAG (Web Content Accessibility Guidelines) standards, which recommend a minimum contrast ratio of 4.5:1 for standard text and 3:1 for large text. To improve accessibility, consider using #11088e with lighter backgrounds or pairing it with text colors that offer better contrast, such as white or light yellow. When using #11088e for decorative elements, ensure that the visual information is not solely conveyed through color, as colorblind users may not be able to perceive the difference. Providing alternative cues, such as text labels or patterns, can enhance accessibility for a wider audience. Additionally, tools like contrast checkers can help evaluate and adjust color combinations for optimal readability and usability.
