General Information about Congress Blue

The color #0F438B, also known as Congress Blue, is a dark, muted shade of blue that conveys a sense of depth, stability, and sophistication. It is often associated with authority, trust, and intelligence, making it a popular choice for corporate branding, government institutions, and academic environments. This color is created by combining a low amount of red (0F), a moderate amount of green (43), and a high amount of blue (8B) in the hexadecimal color system. Its RGB values are approximately R:15, G:67, and B:139. In CMYK, it consists of high percentages of cyan and magenta, and a moderate amount of black, resulting in its deep, rich tone. Congress Blue is often used to create a sense of calmness and reliability, while maintaining a professional and formal appearance.

The hex color #0F438B, also known as Congress Blue, presents some accessibility challenges, especially when used as a background color for text. Due to its dark nature, it requires very light text (white or near-white) 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. Using #0F438B with dark or even moderately dark text will likely fail these contrast requirements, making the content difficult to read for users with visual impairments. Therefore, when incorporating this color, it is crucial to meticulously test the color combinations with accessibility tools to confirm compliance and ensure the design is inclusive and user-friendly. Consider using a lighter shade of blue or a different color altogether if sufficient contrast cannot be achieved.
