The color #0247B2, a deep cobalt blue, presents some accessibility challenges, especially for users with visual impairments. When used as a background color, it requires a very light text color to ensure sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to meet WCAG AA standards. Using online contrast checkers is crucial to verify compliance. For users with color blindness, relying solely on this color to convey information is not advisable.
