The hex color #2F49B7, also known as Cerulean Blue, presents some accessibility considerations for web developers. Its relatively low luminance can create insufficient contrast when used as text on a white or very light background, potentially hindering readability for users with visual impairments. 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 #2F49B7 for text, developers should pair it with a sufficiently light or dark background color to meet these contrast requirements. Tools like contrast checkers can help evaluate color combinations. Additionally, avoid relying solely on color to convey important information, as colorblind users may not be able to distinguish it effectively. Providing alternative cues, such as text labels or icons, can improve accessibility for all users.
