The color #0D4D8A, also known as Congress Blue, presents some accessibility challenges, particularly when used as text on a white background. Its relatively low luminance results in a contrast ratio that may not meet WCAG (Web Content Accessibility Guidelines) standards for normal-sized text. To ensure readability for users with visual impairments, it's crucial to use this color with larger text sizes or pair it with a lighter background. When using this color for interactive elements like buttons or links, providing sufficient contrast is important, indicated through a contrast ration calculation. For example, a lighter shade of blue or a contrasting color like yellow or orange can be used for the text or background to improve accessibility. Tools like contrast checkers can help determine if the contrast ratio meets accessibility standards and avoid difficulties with color blindness. Therefore, careful consideration of contrast is necessary when using #0D4D8A to create inclusive and accessible designs.
