This is a color most often used when the mood is one of mystery.

The color #280021, a deep, muted purple, presents significant accessibility challenges, particularly in text-based applications. Its low luminance value of approximately 2% results in very poor contrast against standard light backgrounds, failing WCAG standards for text legibility. Using this color for text on a white or light-colored background would make it exceptionally difficult for individuals with visual impairments, including those with low vision or color blindness, to read the content. To ensure accessibility, it is imperative to avoid using #280021 for text or essential UI elements unless paired with a very light color such as almost white. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended by WCAG. This is unlikely to be achieved without substantial lightening of the foreground or darkening of the background. When using this color, provide high contrast alternative themes and avoid relying on color alone to convey information.
