The color #2A4AC7, also known as Cerulean Blue, presents some accessibility challenges primarily due to its relatively low luminance. When used as text against a white background, it may not meet the contrast ratios recommended by WCAG (Web Content Accessibility Guidelines) for readability, particularly for users with visual impairments. A contrast ratio of at least 4.5:1 is generally recommended for standard text and 3:1 for large text. Using this color for text requires careful consideration of font size and weight. To improve accessibility, consider pairing it with lighter backgrounds or using it for larger text elements. Another option is to add a darker shade as a text-shadow. When used for interactive elements such as buttons or links, ensure sufficient visual cues are provided to indicate the interactive state, such as hover or focus effects. Providing alternative text for images that use this color is also crucial for screen reader users. Testing the color combination with accessibility evaluation tools helps to ensure compliance with accessibility standards.
