The perceived color can vary based on lighting conditions and screen calibration.

The hex color #190430, also known as Black Rock, presents several accessibility challenges, especially in web design. Its very low luminance of approximately 1% makes it difficult to read text or discern interface elements against this background for users with normal vision. The contrast ratio against white (#FFFFFF) is approximately 16.8:1, which technically meets WCAG AAA standards for large text (18pt or 14pt bold) but falls short for regular text. This means that using white text on a #190430 background requires the text to be significantly large to be considered accessible. To improve accessibility, consider using lighter colors for text or interface elements on this background, or using #190430 as an accent color rather than the primary background. Also, consider using a tool to simulate colorblindness when designing, as dark colors can sometimes be difficult to distinguish for users with certain types of colorblindness.
