A contrast ratio of at least 4.5:1 is generally recommended for normal text and 3:1 for large text. Therefore, when using Cerulean Blue for text, consider pairing it with lighter background colors like white, off-white, or very light grays to ensure readability. Alternatively, using it for interactive elements requires careful consideration to ensure sufficient contrast with the element's background and surrounding text. Using a color contrast checker is advisable to verify compliance with accessibility standards. Furthermore, consider providing alternative visual cues, such as icons or text labels, to enhance usability for all users, including those with color blindness. Ensuring proper focus indicators on interactive elements is crucial for keyboard navigation.
