The hex color #2e5cb5, also known as Cerulean Blue, presents some accessibility considerations for web developers. Its contrast ratio with white text is approximately 3.5:1, which falls short of the WCAG AA standard of 4.5:1 for normal-sized text.

To improve accessibility, developers should consider using a lighter shade of blue or using darker text colors like black or dark gray which offers a much better contrast ratio. Employing tools to test color contrast is crucial during the design process. The color should be tested on diverse screens sizes and devices, as well as taking into consideration of accessibility concerns for color blind users.
