The color #213A5B, a deep shade of blue often referred to as Cello, presents some accessibility considerations for web developers. Its relatively low luminance value means it requires careful pairing with contrasting colors to ensure readability, especially for users with visual impairments. When used as a background color, it necessitates light-colored text to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Developers should use tools to check the contrast ratio between text and background colors. Furthermore, avoid using this color as the sole means of conveying information, such as in error messages or status indicators, as colorblind users may not be able to differentiate it from other colors. Supplement color cues with text labels, icons, or patterns to ensure universal accessibility. When using this color for interactive elements like buttons or links, ensure that hover and focus states provide sufficient contrast to indicate interactivity clearly.
