The hex color #28355B, also known as Cello, presents certain accessibility considerations, especially in web design. When used as a background color, it is crucial to ensure sufficient contrast with the foreground text to meet WCAG guidelines. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This dark, muted blue can pose challenges if paired with similarly dark text colors. Using a light color like white, or a bright yellow or green for text, can significantly improve readability. Additionally, avoid relying solely on color to convey important information, as users with color vision deficiencies may not be able to distinguish between certain colors. Providing alternative cues, such as text labels or icons, is essential for inclusive design. When used for interactive elements, focus states should be clearly visible to aid keyboard navigation.
