This color resides in the blue-purple hue range and exhibits a relatively low saturation and brightness.

The color #140A2A, also known as Black Rock, presents significant accessibility challenges, especially when used as a foreground color against a white or light background. Its low luminance results in very poor contrast, making it difficult for users with visual impairments, including those with low vision or color blindness, to distinguish text or interface elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Black Rock falls far short of these recommendations, potentially excluding a large segment of users. To improve accessibility, consider using Black Rock sparingly, if at all, for text or interactive elements. When it is necessary, pair it with a very light color, ensuring the contrast ratio meets accessibility standards, or use it for decorative purposes only. Always use color contrast analyzers to verify the contrast ratio meets the minimum standards. Providing alternative color themes that offer better contrast options could greatly improve usability.
