It should be used with careful consideration of contrast ratios to maintain accessibility standards.

The hex color #11082B, also known as Black Rock, presents significant accessibility challenges. Its extremely low luminance results in very poor contrast against standard white backgrounds, making it difficult for users with visual impairments to read text or distinguish elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Black Rock falls far below these recommendations. To improve accessibility, it's crucial to pair this color with much lighter shades, such as yellows, light blues, or whites. Avoid using it for critical elements like buttons or links unless the contrast is significantly enhanced. Consider using a color contrast checker to ensure compliance with accessibility standards and provide a better user experience for everyone, especially those with low vision or color blindness.
