The hex color #0B34A9, also known as International Klein Blue, presents specific accessibility considerations for web developers. Its dark hue results in a low luminance value, which means it requires careful pairing with text and other visual elements to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text. Therefore, when using #0B34A9 as a background, it is crucial to use light-colored text, such as white or light yellow, to meet these contrast requirements. Failing to do so can result in readability issues, especially for users with visual impairments. In addition, avoid using this color for essential user interface components without proper contrast, as it can hinder usability and accessibility. Always test the color combination with accessibility tools to ensure compliance with accessibility standards and provide an inclusive user experience.
