The hex color #2E49B8, also known as Cerulean Blue, presents some accessibility challenges, especially when used as a foreground color on a white or light background. Its luminance is relatively low, which means the contrast ratio might not meet WCAG (Web Content Accessibility Guidelines) standards for text legibility. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. To improve accessibility, consider using #2E49B8 with lighter text or interface elements against a darker background. Alternatively, pairing it with a much lighter shade of blue or a contrasting color like yellow or orange can help ensure readability and usability for users with visual impairments. Testing the color combination with accessibility tools is crucial to guarantee compliance and optimal user experience. Also consider using a text size of at least 14 points or larger for better readability.
