The hex color #1F3A4A, also known as Nile Blue, presents some accessibility challenges due to its relatively low contrast against lighter backgrounds. When used for text, it's crucial to ensure sufficient contrast ratio with the background color to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Tools like contrast checkers can help verify compliance. Using a lighter text color like white or a very pale yellow on a #1F3A4A background could improve readability. Similarly, when used for interactive elements like buttons, ensure clear visual cues for focus states. Consideration should also be given to users with color vision deficiencies; testing with color blindness simulators is advisable. A simple fallback is to provide additional non-color cues such as underlines or icons to ensure accessibility for all users.
