It is a color frequently used in corporate branding and government-related contexts due to its association with seriousness and professionalism.

It is often perceived as calming and reassuring, which can be beneficial in environments that require a sense of order and control.

The hex color #004780, also known as Congress Blue, presents some accessibility challenges, especially when used as a background color for text. Its relatively low luminance means that text must be a light color to provide sufficient contrast. 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 (14 points bold or 18 points regular). When using #004780, ensure that any text displayed on top of it meets these contrast requirements. Lighter shades of white, yellow, or even pale blues or greens may work well as text colors. Tools like the WebAIM contrast checker can be valuable for verifying compliance. Also, avoid using this color for interactive elements without clear visual cues, as users with visual impairments may have difficulty perceiving them.
