The hex color #234eb3, Cerulean Blue, presents some accessibility challenges, particularly regarding color contrast. When used as a background color, it requires careful selection of foreground text colors to ensure readability. White text generally offers the best contrast against this dark blue hue, meeting WCAG (Web Content Accessibility Guidelines) standards for normal text (AA compliance) and larger text (AAA compliance). Conversely, using lighter shades of blue, gray, or even yellow can result in insufficient contrast, making the content difficult to read for users with visual impairments.

Consideration should also be given to users with color blindness, as they may perceive the color differently. Providing alternative cues, such as icons or text labels, can further enhance accessibility.
