The hex color #2B4BBB, also known as Cerulean Blue, presents some accessibility challenges, particularly regarding color contrast. When using this color for text or interactive elements, it is crucial to ensure sufficient contrast against the background. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Given Cerulean Blue's relatively dark nature, it is advisable to pair it with light colors like white (#FFFFFF) or very pale yellow to meet these contrast requirements. Tools like WebAIM's contrast checker can be used to verify compliance. Failure to meet these guidelines can make content difficult or impossible to read for users with visual impairments. Also, avoid using #2B4BBB as the sole indicator for important actions or information, as colorblind users may not be able to distinguish it. Consider adding secondary indicators, such as text labels or icons.
