General Information about Congress Blue

Congress Blue, with the hex code #0B4889, is a deep, muted shade of blue that evokes feelings of stability, trust, and professionalism. It belongs to the blue color family, known for its calming and serene qualities. This particular shade is often associated with authority and reliability, making it a popular choice for corporate branding and government-related entities. In color psychology, blue is linked to intelligence, efficiency, and thoughtfulness. It's a versatile color that can be used in a variety of applications, from web design to interior decorating, to create a sense of confidence and competence. Its relatively low saturation and moderate lightness make it suitable for both backgrounds and text, although careful consideration of contrast is necessary to ensure readability.

The color #0B4889, also known as Congress Blue, presents some accessibility challenges, particularly concerning color contrast. When used as text against a white background, it may not meet WCAG (Web Content Accessibility Guidelines) requirements for contrast ratio, potentially making it difficult for users with visual impairments to read. To improve accessibility, consider pairing Congress Blue with lighter colors like white, light gray, or a contrasting yellow or orange. Additionally, when using this color for interactive elements like buttons or links, ensure sufficient contrast is provided in different states (hover, focus, active) to ensure usability for all users, including those with cognitive disabilities. Aim for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text and graphical elements. Implementing these considerations will make your design more inclusive and user-friendly.
