The color #1A3B5D, a deep, muted blue, presents some accessibility challenges. Its low luminance value means that it has a relatively low contrast ratio against lighter backgrounds, particularly white. When using this color for text, it is crucial to ensure sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards, specifically a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Using this color for interactive elements requires careful consideration. Ensure that hover, focus, and active states are clearly distinguishable, not only in color but also with visual cues like borders or changes in shape. This is especially important for users with visual impairments or color blindness, as relying solely on color change may not be sufficient. When pairing this color with others, choose lighter or more vibrant hues to create necessary contrast. In data visualizations, avoid using #1A3B5D to represent critical information if other colors with similar luminance are also present. Proper planning and testing are essential to ensure content using this color is accessible to all users.
