The hex color #1f4fcb, also known as Cerulean Blue, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, the contrast ratio may not meet WCAG (Web Content Accessibility Guidelines) standards for Level AA compliance, which requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. This means users with moderate visual impairments may struggle to read content using this color. Therefore, it is crucial to ensure sufficient contrast by pairing it with a lighter background or using it for larger text elements. To improve accessibility, consider using a lighter shade of blue or a completely different color for text. Additionally, avoid using this color alone to convey important information, instead using text labels or icons for clarity.
