The color #1F3A5F, also known as Cello, presents specific accessibility considerations for web developers. Its relatively low lightness value results in a dark appearance, which necessitates careful selection of foreground 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 #1F3A5F as a background, lighter colors such as white (#FFFFFF) or pale yellows are advisable for text to meet these contrast requirements.

Providing supplementary cues like text labels or icons ensures inclusivity and enhances the user experience for everyone.
