The hex color #2255bb, also known as Cerulean Blue, presents some accessibility challenges, particularly for users with visual impairments. With a relatively low luminance, text rendered in this color may lack sufficient contrast against a white or light background, making it difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. To improve accessibility, consider pairing #2255bb with lighter colors such as white (#ffffff), light gray (#dddddd), or a pale yellow (#ffffcc) for text. For background usage, ensure foreground elements have adequate contrast. Utilizing online contrast checkers can help evaluate color combinations to meet accessibility standards. Moreover, avoid relying solely on color to convey important information, as colorblind users may not perceive the intended message. Always provide alternative cues, such as text labels or icons, to ensure inclusivity.
