This color is often used in art, design and webdesign.

The hex color #20009b, a deep ultramarine, presents accessibility challenges due to its low luminance. When used as a background color, sufficient contrast with foreground text is crucial for readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Light colors like white, light yellow, or pale green would provide adequate contrast. Using online contrast checker tools is advisable to ensure compliance. Additionally, consider providing alternative visual cues, such as icons or borders, to convey information beyond color alone. For users with cognitive disabilities, avoid using this color for critical information as it may be difficult to distinguish. Employing clear and concise language is essential to complement the visual design.
