The hex color #004F98, also known as Congress Blue, presents some accessibility considerations for web developers. Its relatively low luminance means it requires careful pairing with text and background colors to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). When using #004F98 as a background, it's advisable to use light-colored text to meet these contrast requirements. Tools are available to check color contrast ratios and ensure compliance. Insufficient contrast can make content difficult to read for users with low vision or color blindness. Furthermore, avoid using color alone to convey important information; supplement color cues with text labels or other visual indicators.
