The color #172B81, also known as Jackson's Purple, presents significant accessibility challenges, especially when used for text or interactive elements. Its low lightness value (approximately 11%) results in a very dark appearance, requiring careful consideration of contrast ratios. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is necessary for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to ensure readability for users with moderate visual impairments. When using #172B81 as a background color, it is crucial to pair it with a very light text color, such as white (#FFFFFF), to meet these contrast requirements. Tools like the WebAIM contrast checker can be invaluable in verifying compliance. Additionally, avoid using #172B81 for critical visual cues or elements that rely solely on color to convey information, as this can exclude users with color vision deficiencies. Instead, supplement color coding with text labels, icons, or patterns to ensure inclusivity and accessibility for all users.
