The hex color #1C4DBA, also known as Cerulean Blue, presents some accessibility challenges. Its relatively low luminance can cause issues with text legibility, especially when used as a background color with light text. According to WCAG guidelines, sufficient contrast between text and background is crucial 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 #1C4DBA, it's important to carefully select text colors to meet these contrast requirements. Light yellows, oranges, or whites may provide better contrast, but it is essential to test these combinations using accessibility tools to ensure compliance. Additionally, avoid using #1C4DBA for small, detailed graphics or interactive elements, as the lack of contrast can make them difficult to perceive.
