Its use requires careful consideration to ensure readability and accessibility, especially when used for text or interactive elements.

The hex color #040034, also known as Black Rock, presents significant accessibility challenges due to its very low luminance. It falls far short of the contrast ratios recommended by WCAG (Web Content Accessibility Guidelines) for text and interactive elements against a white background. Using this color for text or important UI elements requires careful consideration. Pairing it with very light colors such as white, very light grays, or vibrant yellows or oranges is crucial to achieve acceptable contrast. Even then, the contrast should be tested rigorously using accessibility tools to ensure readability for users with visual impairments. It is generally not recommended for extensive text blocks or elements that demand high visibility. Developers should provide sufficient alternatives and enhanced contrast options, especially for users with low vision or color blindness, to ensure an inclusive user experience. Furthermore, consider larger font sizes to improve readability when using this dark hue.
