The color #0D378A, also known as Congress Blue, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it requires light text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for body text and 3:1 for larger text elements to comply with WCAG (Web Content Accessibility Guidelines). Using a color contrast checker is advisable to verify compliance. Individuals with visual impairments might find it difficult to distinguish elements with insufficient contrast. Therefore, careful consideration of text and interactive elements is crucial. Avoid pairing this dark blue with other dark hues. Lighter shades of yellow, white, or even light grays can significantly improve accessibility. The color should be tested to see if it works with different screen resolutions and for people with different types of colorblindness.
