The hex color #0D3E8B, also known as Congress Blue, presents several accessibility considerations for web developers. Its dark hue results in a low luminance value, which means it requires careful pairing with text and other elements to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #0D3E8B as a background, light-colored text (e.g., white or very light yellow) should be used to meet these contrast requirements. Tools like contrast checkers can help verify compliance. Additionally, avoid using this color as the sole indicator of interactive elements, such as links, as users with color vision deficiencies may not be able to distinguish them. Always provide alternative visual cues like underlines or icons to enhance accessibility.
