The hex color #1e2a84, also known as Jackson's Purple, presents some accessibility challenges, particularly in text-based applications. Its relatively low luminance value of 0.034 means that it needs to be paired with very light text colors, such as white or very light grays, to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to meet AA compliance. When using #1e2a84 as a background, careful consideration must be given to the foreground text color to meet these contrast requirements. Tools like contrast checkers can be invaluable in determining appropriate color pairings. Also, avoid using this color for essential visual elements like icons or buttons without sufficient contrast, as it may not be perceivable by users with low vision or color blindness. Providing alternative visual cues, such as labels or shapes, can further enhance accessibility.
