The hex color #2458B2, also known as Cerulean Blue, presents specific accessibility considerations for web development. Its relatively low lightness value implies that sufficient contrast with text and other elements is essential to ensure readability and usability, especially for users with visual impairments.

Consideration should also be given to the overall design and user experience when incorporating this color into a website or application.
