The hex color #0A4B8E, also known as Congress Blue, presents some accessibility considerations for web development. Its relatively dark hue means that it requires light-colored text 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 #0A4B8E as a background color, it's essential to choose a foreground color that meets these contrast requirements. White (#FFFFFF) or very light grays are generally good choices. Tools like contrast checkers can help verify compliance. Conversely, using dark text colors on a #0A4B8E background would likely result in poor readability, especially for users with visual impairments. Careful consideration of color combinations is vital to ensure an inclusive and accessible user experience.
