The hex color #0047ca, also known as Cobalt, presents some accessibility challenges, primarily due to its relatively low luminance. When used as a foreground color, it requires careful consideration of the background color to ensure sufficient contrast for readability. 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. Using #0047ca on a white background, for example, would likely fail these contrast requirements. To improve accessibility, consider pairing it with lighter shades of yellow, white, or gray to achieve an acceptable contrast ratio. Alternatively, #0047ca can be effectively used for decorative elements where readability is not critical. Tools like contrast checkers can help evaluate and adjust color combinations for optimal accessibility. When used for interactive elements, ensure sufficient visual cues beyond color alone, such as underlines or icons, to accommodate users with color vision deficiencies. Thoughtful application enhances the user experience for everyone, regardless of visual ability.
