The color #090D2C, also known as Black Rock, presents some accessibility challenges, especially concerning text readability. Due to its very dark nature, using it as a background color requires careful consideration of the foreground text color. A light or bright color is essential to ensure sufficient contrast, meeting WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Without adequate contrast, users with visual impairments may struggle to read the content.

Proper implementation of ARIA attributes can further improve accessibility, providing screen readers with information about the purpose and state of elements using this color.
