The color #0C3EA8, a deep cobalt blue, presents some accessibility considerations for web design. When used as a background color, it requires careful selection of foreground text colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. White and light shades of yellow or green are often good choices to contrast effectively with this dark blue. Conversely, avoid using dark text colors like black, gray, or similar shades of blue, as they would not provide enough contrast, making the content difficult to read for users, especially those with visual impairments. It's crucial to test color combinations with accessibility tools to verify compliance. When used for interactive elements, consider providing additional cues such as underlines or icons, to reinforce the visual distinction for users who might not perceive color differences effectively. Proper consideration of color blindness is also important, and using a color contrast analyzer is recommended to ensure readability.
