Due to its low brightness, it can create a feeling of depth, mystery and seriousness. It should be used carefully with other colors to make sure there is enough contrast.

The hex color #040431, also known as Black Rock, presents significant accessibility challenges, especially in web design. Its extremely low luminance means that text or interactive elements using this color as a background would require very light foreground colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #040431 may make it difficult to meet these standards, potentially excluding users with visual impairments. Careful consideration must be given to color pairings. Lighter shades of grays, yellows or white would need to be used for text, combined with sufficient size and thickness to ensure readability. Always testing with accessibility tools is recommended to confirm compliance.
