The color #2B4CAB, a deep sapphire blue, presents some accessibility challenges, especially regarding color contrast. When used as a background color, it necessitates very light text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular). Using a color contrast checker is essential to verify compliance with WCAG guidelines. This color may not be suitable for users with visual impairments if proper contrast is not achieved. It is crucial to test the color combination with various accessibility tools and, ideally, with real users to ensure an inclusive design. Consideration should also be given to users with color vision deficiencies who may perceive this color differently. Using icons and labels in addition to color can improve usability for a broader audience. Furthermore, avoid using this color as the sole indicator of important information.
