The hex color #103D8B, also known as Congress Blue, presents some accessibility challenges due to its relatively low luminance. When used as a background color, it's crucial to ensure sufficient contrast with text or foreground elements to meet WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This can be achieved by pairing it with lighter colors such as whites, creams, or very light yellows. Tools like contrast checkers can help determine if the contrast ratio is adequate. Avoid using #103D8B for essential UI elements like buttons or links if the contrast is insufficient, as this can create usability issues for users with visual impairments. Providing alternative color schemes that offer better contrast is also a good practice.
