The color #10148B, also known as Ultramarine, presents certain accessibility challenges, particularly concerning color contrast. When used as a background color, it's crucial to pair it with text that is sufficiently light to ensure readability. White and very light shades of yellow or green are preferable. Avoid using dark or similarly toned colors for text or interactive elements, as the contrast ratio would likely fall below the WCAG (Web Content Accessibility Guidelines) recommended levels. A contrast ratio of at least 4.5:1 for standard text and 3:1 for large text is recommended to ensure compliance with accessibility standards. When utilizing this color, consider providing alternative visual cues, such as icons or patterns, alongside color to ensure that users with visual impairments can still understand the information being presented. Proper testing with accessibility tools is essential to validate the color choices.
