The color #1C4EBA, a shade of cerulean blue, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color for text or interactive elements, it's crucial to ensure sufficient contrast against the background. According to WCAG (Web Content Accessibility Guidelines), a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a very light background color like white (#FFFFFF) might not meet these contrast requirements, potentially making content difficult for users with visual impairments to read. To improve accessibility, consider pairing #1C4EBA with very light yellows, oranges, or greens. Testing the color combination with accessibility tools is essential to ensure compliance with accessibility standards and provide an inclusive user experience. Also, avoid using this color as the sole indicator of focus or state, and provide alternative visual cues.
