The color #283B4E, also known as Blue Dianne, presents some accessibility considerations for web developers. Its relatively low lightness value can result in insufficient contrast when used as text against a white or very light background. According to WCAG guidelines, sufficient contrast is crucial for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Before using Blue Dianne for text, developers should verify the contrast ratio using online tools or browser extensions. If the contrast is inadequate, consider using a lighter shade of the same hue or a completely different color to ensure content accessibility. For backgrounds, pairing #283B4E with very bright text colors like white or yellow can improve contrast, but testing with accessibility tools is still recommended.
