The hex color #18052F, also known as Black Rock, presents significant accessibility challenges, especially when used for text or interactive elements. Its low luminance value results in a very poor contrast ratio against standard white backgrounds, falling far below the WCAG guidelines for both normal and large text sizes.

Alternatively, explore using this color for purely decorative purposes where contrast is not a primary concern.
