The hex color #2A5BBC, also known as Cerulean Blue, presents some accessibility considerations for web developers. Its contrast ratio against white (#FFFFFF) is approximately 3.7:1, which falls short of the WCAG 2.1 Level AA standard of 4.5:1 for normal text. Therefore, using #2A5BBC directly on a white background for body text might not be ideal for users with visual impairments. To improve accessibility, developers should consider using a darker shade of blue or a lighter background color to increase the contrast ratio. For larger text (14pt bold or 18pt regular), the contrast ratio meets the WCAG AA standard. Alternatively, this color can be used for decorative elements or accents where the contrast requirements are less stringent. Always test color combinations with accessibility tools to ensure compliance with accessibility guidelines and provide a better user experience for everyone.
