The color #0D4E8B, also known as Congress Blue, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it's crucial to select text colors that provide sufficient contrast to ensure readability for users with visual impairments. 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. White or very light shades of yellow and orange could potentially work well as text colors. Tools like contrast checkers can precisely determine the contrast ratio. It is not recommended to use this color for text. Also, avoid pairing it with similar dark colors. Ensure interactive elements using Congress Blue have other visual cues besides color, such as underlines or borders, to aid users with color blindness.
