The hex color #0A3B91, also known as Congress Blue, presents specific accessibility considerations for web developers. Its dark hue implies that it requires careful selection of foreground text 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. Using white or light yellow text on a #0A3B91 background typically meets these contrast requirements, making the content easily readable for individuals with visual impairments. However, it's crucial to test color combinations using accessibility tools to guarantee compliance. Furthermore, avoid using this color for interactive elements without clear visual cues, as color alone should not convey important information. Incorporating additional indicators such as underlines or icons helps to ensure usability for all users, including those with color vision deficiencies.
