The color #2B4FBB, also known as Cerulean Blue, presents some accessibility challenges, particularly when used for text or interactive elements. Its relatively low lightness value (around 36%) means that it requires careful consideration of contrast ratios against background colors. To ensure readability and usability, it's crucial to pair it with a sufficiently light background, aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text, as specified by WCAG guidelines. Using tools to evaluate color contrast is highly recommended during the design process. Also, avoid using this color as the sole indicator of functionality, such as in links or buttons, as users with color vision deficiencies may not be able to distinguish it effectively. Supplement color with other cues like underlines or labels to enhance accessibility.
