The hex color #28009b, also known as Blue Gem, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in low contrast against light backgrounds, making text and other elements difficult to discern. According to WCAG guidelines, sufficient contrast ratios are crucial for readability. To improve accessibility, consider using #28009b primarily for decorative elements or large graphical areas. When using it for text or interactive elements, pair it with a very light color such as white (#ffffff) or a pale yellow. Ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular) to meet WCAG AA standards. For AAA compliance, aim for even higher contrast ratios. Additionally, avoid using #28009b as the sole indicator of interactive elements; supplement it with other cues like underlines or icons to enhance usability for all users.
