It is also a non-spectral color, since it is not found on the visible spectrum or in the rainbow.

The hex color #020519, also known as Blue Charcoal, presents significant accessibility challenges, particularly in web design. Its extremely low luminance makes it difficult to achieve sufficient contrast against lighter backgrounds, potentially violating WCAG (Web Content Accessibility Guidelines) standards. Text or interactive elements using this color on a white or light-colored background may be illegible for users with visual impairments. To ensure accessibility, consider pairing #020519 with much lighter colors, and conduct thorough contrast ratio testing. Tools like WebAIM's Contrast Checker can help. Also, avoid using it for crucial interactive elements without proper indication and testing with users with disabilities.
