General Information about Congress Blue

Congress Blue, represented by the hexadecimal color code #0B3F8D, is a dark shade of blue that exudes sophistication and professionalism. It is often associated with authority, trustworthiness, and stability, making it a popular choice for corporate branding, government institutions, and academic settings. This deep blue hue is created by combining relatively low levels of red and green with a high level of blue in the RGB color model. In the CMYK color model, it requires a significant amount of cyan and magenta, with a moderate amount of yellow and black. Its low lightness value in the HSL color space contributes to its depth and richness, giving it a dignified and serious aesthetic. The color's name suggests a connection to governmental and political spheres, further reinforcing its associations with power and integrity.

The color #0B3F8D, a deep shade of blue, presents some accessibility challenges, especially in web design. Its low lightness value means that text using this color as a background will require a very light foreground color to meet WCAG (Web Content Accessibility Guidelines) standards for contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. When using #0B3F8D for interactive elements like buttons or links, sufficient visual cues beyond color alone should be provided, such as underlines or borders, to assist users who are color blind. Careful consideration of these factors will help ensure that content using this color is accessible to a wider audience.
