The hex color #0347B1, also known as Cobalt, presents some accessibility challenges, especially regarding text legibility. Due to its dark hue, using it as a background color requires careful consideration of the foreground text color. A light color, such as white (#FFFFFF) or a pale yellow (#FFFFE0), would provide sufficient contrast to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (4.5:1 contrast ratio) and large text (3:1 contrast ratio). Avoid using it for interactive elements like buttons or links unless a clear visual indicator, like a contrasting border or hover effect, is added. When used for non-text elements, ensure that the color provides sufficient contrast against adjacent colors to differentiate the element. Remember to test color combinations using accessibility tools to ensure compliance with accessibility standards and provide an inclusive experience for all users, including those with visual impairments.
