The color #09009B, a deep ultramarine, presents significant accessibility challenges. Its extremely dark hue results in very low contrast against typical light backgrounds like white. This severely impacts readability for users with visual impairments, including those with low vision or color blindness. Text rendered in #09009B on a white background would be difficult, if not impossible, for many users to discern. According to WCAG guidelines, the contrast ratio must be at least 4.5:1 for normal text and 3:1 for large text to meet Level AA compliance. This color likely fails to meet these standards against most light backgrounds. To improve accessibility, consider using #09009B sparingly, primarily for decorative elements or accents. When used with text, pair it with a very light color, such as white or a pale yellow, and verify the contrast ratio using an online contrast checker. Using a darker shade of yellow or a lighter shade of blue may also help in making the content accessible.
