The hex color #130B2B, also known as Black Rock, is a very dark, muted shade that sits within the purple-blue range of the color spectrum. It has a relatively low saturation and lightness, contributing to its somber and understated appearance. In the RGB color model, it is composed of 7.45% red, 4.31% green, and 16.86% blue. When converted to the CMYK color model, it consists of 56% cyan, 74% magenta, 0% yellow, and 83% black. This color can evoke feelings of mystery, depth, and sophistication. It is often used in designs where a subtle, yet impactful, dark hue is desired. The color is perceived as cool due to the higher proportion of blue relative to red and green.

The hex color #130B2B presents significant accessibility challenges, particularly in text-based applications. Its very low lightness value (being a very dark color) results in poor contrast against most background colors, including white. This lack of contrast can make text difficult or impossible for users with visual impairments to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to meet Level AA conformance. #130B2B will likely fail these tests against many common background colors. Web developers should avoid using this color for text without careful consideration of contrast. It's crucial to pair it with very light colors to ensure readability and meet accessibility standards. Using contrast checking tools is highly recommended. Non-text elements may need a contrast ratio of 3:1, even then careful consideration needs to be taken into account.
