The color #1F3A4E, also known as Nile Blue, presents some accessibility challenges, particularly when used as text on a white or light background. Its relatively low luminance means that the contrast ratio may not meet WCAG (Web Content Accessibility Guidelines) standards for readability. To ensure accessibility, it's crucial to pair it with a sufficiently light color for text or a significantly darker color for backgrounds to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using a contrast checker tool is highly recommended to verify compliance. When using #1F3A4E for interactive elements like buttons or links, providing clear visual cues beyond color alone (e.g., underlines, borders, icons) is important for users with color vision deficiencies. Also consider the context in which the color is used. For purely decorative purposes, contrast requirements may be less stringent, but for any content that conveys information, sufficient contrast is essential.
