The hex color #1B5699, also known as Fun Blue, presents some accessibility challenges, especially when used as a background or text color. Its relatively low lightness value means that it requires careful consideration of contrast ratios to ensure readability for users with visual impairments. According to WCAG guidelines, sufficient contrast is essential for text and interactive elements to be perceivable. For normal text (14 points or 18.66 pixels and larger, or bold text at 12 points or 16 pixels), a contrast ratio of at least 4.5:1 is recommended against its background. For large text, the requirement is reduced to 3:1. When using #1B5699, designers and developers should use color contrast checking tools to verify that the chosen foreground color meets these standards. Light shades of yellow, orange or white could provide sufficient contrast. Failure to meet these contrast requirements can exclude individuals with low vision or color blindness from accessing content. It is also important to consider providing alternative cues, such as underlining links or using icons, to supplement color differences.
