General Information about Congress Blue

Congress Blue, represented by the hex code #10378B, is a deep, muted shade of blue with historical associations to governance and authority. It’s often perceived as a color that conveys trust, stability, and professionalism. In color psychology, darker blues are linked to knowledge, power, integrity, and seriousness. This color finds applications in various fields, ranging from corporate branding to web design, where creating a sense of reliability is paramount. Its relative darkness means it requires careful consideration of contrast when used with text or other design elements to ensure readability and accessibility. The color's subtlety also lends itself well to being paired with both complementary and analogous colors to achieve visual harmony and balance in design projects. Congress Blue is not a particularly common color in nature, further adding to its association with man-made institutions and formal settings.

The hex color #10378B, also known as Congress Blue, presents several accessibility considerations for web development. Its dark hue results in a relatively low contrast ratio against standard white backgrounds. Therefore, using #10378B for text on a white background might not meet WCAG (Web Content Accessibility Guidelines) AA standards, requiring a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. To improve accessibility, consider using lighter text colors like white or very light grays to ensure sufficient contrast. Alternatively, using #10378B as a background color necessitates employing brighter, lighter foreground colors to meet accessibility standards. Employing contrast checking tools is highly recommended to validate the color combination's accessibility compliance before deploying any web content. It's also crucial to consider users with visual impairments who might struggle with low contrast. Thoughtful color choices significantly enhance the user experience for everyone.
