General Information about Congress Blue

The color #003B88, commonly known as Congress Blue, is a deep, rich shade of blue that evokes feelings of trust, stability, and authority. It is often associated with government, education, and financial institutions due to its serious and professional nature. This particular hue is created by the absence of red, a moderate amount of green, and a strong presence of blue in the RGB color model. In the CMYK model, it requires a significant amount of cyan and magenta, with only a small amount of yellow and no black. Its hex code #003B88 provides a specific identifier for digital applications, ensuring consistent reproduction across various media. The color's depth makes it versatile for both foreground and background uses, although careful consideration should be given to contrast for readability.

The hex color #003b88, also known as Congress Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color for text, it requires careful consideration of the background color to ensure sufficient contrast for readability. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Using a very light color like white or light yellow as a background is highly recommended to meet these contrast requirements. When #003b88 is used for decorative elements, the contrast requirements are less strict, but it's still essential to ensure that the color difference is sufficient for users with low vision or color blindness to distinguish the elements effectively. Tools are available to check the color contrast ratio to comply with accessibility standards.
