The color #034A9E, a deep shade of cobalt blue, presents some accessibility challenges. Its low luminance value of approximately 3 means that it requires careful consideration when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background to be considered accessible. When pairing #034A9E with text, a very light color like white (#FFFFFF) or a light yellow is strongly recommended to ensure sufficient contrast. Tools such as contrast checkers can assist in verifying compliance. Avoid using this color for small text or critical interactive elements against dark backgrounds. Enhancements such as text shadows or borders can improve legibility, but contrast should always be the primary consideration for accessibility.
