The hex color #2B5FBB, also known as Cerulean Blue, offers moderate accessibility for web content. When used as a foreground color for text, it requires careful consideration of the background color to ensure sufficient contrast. A lighter background, such as a pale yellow or white, would be necessary to meet WCAG (Web Content Accessibility Guidelines) standards for readability.
