General Information about Congress Blue

Congress Blue, represented by the hex code #033F95, is a deep, saturated shade of blue that evokes feelings of stability, trust, and authority. This color is often associated with governmental institutions, financial organizations, and academic settings, owing to its serious and professional connotations. On the color wheel, it sits between blue and indigo, possessing a slightly darker and more formal appearance than standard blue hues. In color psychology, dark blues are often linked to intelligence, security, and calmness, making them a popular choice for branding and design elements that aim to convey these qualities. Its low luminance value makes it suitable for backgrounds when paired with light-colored text, or as an accent color to add depth and sophistication to a design.

The hex color #033f95, also known as Congress Blue, presents specific accessibility considerations for web developers. Due to its dark hue and low luminance, sufficient contrast is crucial when pairing it with text or other interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against background colors. Using lighter shades of yellow, white, or light gray can help achieve this contrast. Developers should also test color combinations using accessibility tools to ensure readability for users with visual impairments. Additionally, relying solely on color to convey information is discouraged; supplementary cues such as text labels or icons should be provided to ensure usability for all users, including those with color blindness.
