The hex color #2D52B9, a shade of Cerulean Blue, presents moderate accessibility challenges. Its contrast ratio against white is approximately 3.9:1, which meets the WCAG AA standard for normal text but falls short for larger text and graphical elements.

Proper contrast checks and user testing are crucial to ensure that content is perceivable and usable by a wide range of individuals. Utilizing tools to simulate color blindness can further aid in making informed design decisions.
