The color #0347B0, also known as Cobalt, presents some accessibility challenges, especially concerning color contrast. When used as a foreground color for text, it requires careful pairing with a background color to ensure sufficient contrast for readability, particularly for users with visual impairments. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Due to its darkness, #0347B0 works best with very light colors like white (#FFFFFF) or very light yellows to meet these standards. Using it with mid-tone or dark backgrounds can render text illegible. When using Cobalt in UI elements, ensure that interactive elements have sufficient visual cues and size to be easily identified and used by all users, including those with motor impairments. Also consider providing alternative styling options or high-contrast modes for users who need them.
