The color #281A81, a deep Persian Indigo, presents several accessibility considerations. Its low lightness value (approximately 9%) means it offers poor contrast against standard white backgrounds, making text illegible for many users, especially those with visual impairments. According to WCAG guidelines, it fails contrast ratio tests for both normal and large text sizes. To improve accessibility, it is crucial to pair this color with very light shades of yellow, white, or green. For example, using #281A81 as a background color requires foreground text with a significantly higher lightness value to meet minimum contrast ratios. When using this color for interactive elements such as buttons or links, ensure that hover and focus states provide sufficient visual contrast changes to indicate the element's active state. Also, avoid using #281A81 to convey critical information without redundant cues, as color blindness can hinder its perception.
