The hex color #1B1EFD, a deep and vibrant blue, presents both opportunities and challenges for web accessibility. When used as a primary background color, sufficient contrast with foreground text is crucial. A light text color like white or a very pale yellow is generally necessary to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio (at least 4.5:1 for normal text and 3:1 for large text). Using a color contrast checker is highly recommended. Conversely, if #1B1EFD is used for text, the background should be a much lighter shade to ensure readability. Avoid pairing this blue with dark greys or blacks, as this could lead to eye strain and make the content difficult to perceive for users with visual impairments. Careful consideration and testing are essential for inclusive design.
