This color is often associated with sophistication, mystery, and depth. Due to its low luminance value, #130A2B has a limited range of applications and should be used carefully, especially in contexts where accessibility is a concern. The color is often referred to as Black Rock because of its dark appearance.

The hex color #130A2B, also known as Black Rock, presents significant accessibility challenges, particularly in text-based contexts. Its very low luminance value results in extremely poor contrast against typical light-colored backgrounds, failing to meet WCAG (Web Content Accessibility Guidelines) standards for readability. Using this color for text on a white or light gray background would make it nearly impossible for users, especially those with visual impairments, to read the content. To improve accessibility, it's crucial to pair #130A2B with a much lighter color that provides a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using this color for crucial interactive elements like buttons or links without careful consideration of the surrounding colors and the provision of sufficient visual cues. Providing alternative text descriptions for images or icons using this color is also recommended to ensure inclusivity.
