The color #101A8B, Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates light-colored text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as per WCAG guidelines. This specific shade might require careful pairing with colors like white, light yellow, or very pale shades of gray to meet accessibility standards. It's essential to test color combinations using accessibility tools to verify compliance. Also, consider users with visual impairments, ensuring that information isn't conveyed solely through color. Providing alternative visual cues, such as text labels or icons, can enhance accessibility for all users. Using a color contrast checker can help ensure your designs are accessible to a wider audience.
