The hex color #1e4ad6, also known as Cerulean Blue, presents some accessibility considerations for web developers. When using this color for text, it's crucial to ensure sufficient contrast with the background. Due to its relatively moderate luminance, pairing it with a light background (like white or very pale yellow) is generally recommended to meet WCAG (Web Content Accessibility Guidelines) standards for readability. Conversely, using it on a very dark background might not provide enough contrast, making the text difficult to read for users with visual impairments. Developers should use tools to check contrast ratios to ensure they meet the minimum requirements (4.5:1 for normal text and 3:1 for large text). Furthermore, avoid relying solely on color to convey important information; always provide alternative cues like text labels or icons to ensure usability for colorblind users.
