The hex color #2159B5, also known as Cerulean Blue, presents some accessibility challenges, especially when used as a background color with light text. Its luminance is not high enough to provide sufficient contrast for users with visual impairments, potentially making text difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #2159B5, ensure that the text color provides adequate contrast. For example, using white text (#FFFFFF) on a #2159B5 background may not meet the contrast requirements for all users. Consider using a lighter shade of blue or a darker text color to improve readability. Tools like contrast checkers can help determine if the contrast ratio is sufficient. Always test your color combinations with accessibility in mind to ensure an inclusive design.
