The color #140430, also known as Black Rock, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance value results in very poor contrast against white backgrounds, failing WCAG (Web Content Accessibility Guidelines) standards for normal and large text sizes. To ensure readability and usability, it's crucial to pair this color with very light or vibrant hues that provide a sufficient contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Consider avoiding its use for critical information or interactive elements unless paired with an accessible contrasting color. For graphical elements, ensure that color isn't the sole means of conveying information, and provide alternative cues to enhance accessibility for users with visual impairments. Proper use of ARIA attributes can further improve the experience for assistive technology users.
