The hex color #305FB6, also known as Cerulean Blue, presents some accessibility challenges, particularly in text applications. When used as text against a white background, the contrast ratio may not meet the WCAG (Web Content Accessibility Guidelines) requirements for level AA compliance, which mandates a contrast ratio of at least 4.5:1 for normal text. Therefore, it's crucial to pair this color with lighter shades for backgrounds or use it for larger text elements where the contrast is less critical. For improved accessibility, consider using darker shades for text or pairing it with complementary colors that enhance visual contrast. Tools such as contrast checkers can help determine appropriate color pairings to ensure readability and inclusivity for all users, including those with visual impairments. Always prioritize testing your color combinations with real users to validate accessibility.
