The hex color #040331, also known as Black Rock, presents significant accessibility challenges due to its extremely low luminance. Its dark nature results in very poor contrast against typical light backgrounds, such as white (#FFFFFF) or light gray (#D3D3D3). This poses readability issues for users, especially those with visual impairments or color vision deficiencies. Adhering to WCAG (Web Content Accessibility Guidelines) is crucial when using this color. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text.

Careful consideration and testing with accessibility tools are essential to guarantee a usable and inclusive experience.
