In color psychology, blue is known to promote calmness and serenity, while also suggesting intelligence and confidence.

Its low saturation makes it suitable for backgrounds and text, although careful consideration should be given to contrast to ensure readability.

The hex color #01479A, also known as Congress Blue, presents some accessibility challenges, particularly for users with visual impairments. Its low lightness value of 0.01 makes it difficult to achieve sufficient contrast with text or other page elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. This color may not meet these requirements when paired with lighter shades, potentially making content difficult to read. To enhance accessibility, consider using lighter text colors like white or very pale yellows to ensure adequate contrast. Alternatively, using a darker shade of blue or a completely different, more contrasting color palette would significantly improve readability for a wider range of users.
