The hex color #104588, also known as Congress Blue, presents some accessibility considerations for web design. Its relatively low lightness value means that it requires careful attention to contrast ratios when used with text or other interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. When using #104588 for text, ensure that the background color is sufficiently light to meet these contrast requirements. White (#FFFFFF) or very light grays are often good choices. If using #104588 as a background, opt for light-colored text to ensure readability. Tools like WebAIM's Contrast Checker can be invaluable in verifying adequate contrast. Also, avoid using color alone to convey important information; always provide redundant cues such as text labels or icons.
