The color #1711A3, Ultramarine, presents significant accessibility challenges, primarily due to its low luminance. Its contrast ratio against white (#FFFFFF) is quite low, making text and other elements rendered in this color difficult for users with visual impairments to discern. To improve accessibility, it's crucial to pair Ultramarine with significantly lighter colors to ensure sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) standards. Using tools to check color contrast is highly advisable during the design process. Moreover, avoid using Ultramarine as the sole indicator of important information; supplement it with text labels or icons to ensure usability for all users, including those with color blindness. Careful consideration of font sizes and weights can also mitigate some of the readability issues associated with low contrast.
