The hex color #0D3C8A, also known as Congress Blue, presents some accessibility challenges, especially when used as a background or text color. Its relatively low luminance value of 0.027 necessitates careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text against its background to ensure readability for users with visual impairments. When using #0D3C8A for text, pairing it with a light color like #FFFFFF (white) or a light shade of yellow can significantly improve readability. Conversely, using darker colors may result in insufficient contrast, making it difficult for users to distinguish text from the background. For background applications, lighter text colors and bold fonts should be considered to enhance accessibility. Tools like contrast checkers can help evaluate the compliance of color combinations with accessibility standards.
