The hex color #2a56bc, also known as Cerulean Blue, presents some accessibility challenges in web design. Its contrast ratio with white text is relatively low, which could make content difficult to read for users with visual impairments. Aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text, as recommended by WCAG guidelines, is essential. To improve accessibility, consider using this color with lighter shades of text or pairing it with darker background colors that provide sufficient contrast.

Testing with accessibility tools is crucial to validate color choices.
