The color #0A4BAA, also known as Cobalt, presents some accessibility challenges, especially in text-based applications. Its relatively low luminance value necessitates 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 standard text and 3:1 for large text. When using #0A4BAA as a background, pairing it with white (#FFFFFF) or very light shades of gray can provide adequate contrast. Conversely, avoid using dark text colors like black (#000000) or dark grays, as they will likely fail accessibility standards. Tools like contrast checkers can be invaluable in verifying compliance. Additionally, consider providing alternative visual cues beyond color alone to convey information, benefitting users with color vision deficiencies. For instance, using icons, patterns, or text labels in conjunction with color can improve accessibility.
