The hex color #1E49B8, also known as Cerulean Blue, presents some accessibility challenges. Its relatively low luminance value of approximately 0.11 means that using it as a background color requires careful consideration of text color choices. To ensure readability and accessibility for users with visual impairments, it is crucial to use a light-colored text, such as white or a very light gray, with a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools like contrast checkers can help in verifying compliance. Avoid pairing it with dark or similarly shaded colors as text, as this would make the content difficult to read. When using this color for interactive elements such as buttons or links, provide sufficient visual cues and consider using focus indicators that are easily discernible.
