Cerulean Blue, represented by the hex code #214FC5, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color, it's essential to pair it with a background color that offers sufficient contrast to ensure readability for individuals with visual impairments. 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.

Thoroughly testing your color combinations with accessibility tools is crucial to ensure an inclusive user experience.
