The color #2A53BC, a shade of Cerulean Blue, presents some accessibility considerations for web developers. When used as a background color, it necessitates careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text.

Furthermore, consider how the color appears to users with different types of color vision deficiencies. Testing with simulation tools can help identify potential issues and guide design choices for a more inclusive user experience.
