The hex color #2A4DCC, also known as Cerulean Blue, presents some accessibility challenges. Its relatively low luminance can create issues with contrast, especially when used as a background for light-colored text. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, particularly for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #2A4DCC, it is important to carefully choose text colors that meet these contrast requirements to ensure that content is accessible to all users. Tools are available to measure the contrast ratio between two colors to help developers make informed decisions. It is also important to consider that color should not be the only means of conveying information, as some users may not be able to perceive color differences.
