The hex color #034395, also known as Congress Blue, presents some accessibility challenges, especially when used for text. Its low lightness value (approximately 3%) means it provides insufficient contrast against common background colors like white. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color will likely fail these requirements when paired with light backgrounds, making it difficult for users with visual impairments to read. To improve accessibility, consider using a lighter shade of blue or pairing it with a very light background color to ensure sufficient contrast. Using tools to check color contrast ratios is highly recommended when using this color in web design to prevent accessibility issues.
