General Information about #0F0034

The hex color #0F0034, sometimes referred to as 'Black Rock', is a very dark shade of purple, nearing black. It is composed of 5.9% red, 0% green, and 20.4% blue. In the RGB color space, it is defined by the values R:15, G:0, and B:52. The HSL representation is H:257.3 degrees, S:100%, L:10.2%. Its primary characteristic is its low luminance, rendering it a challenging color for many applications, especially regarding accessibility. This color evokes a sense of mystery, depth, and understated elegance due to its near-black appearance. The name 'Black Rock' suggests a connection to geological formations and natural elements, linking the color to the strength and steadfastness associated with rocks and the richness of darkness.

The hex color #0F0034, also known as Black Rock, presents significant accessibility challenges, particularly in text-based applications. Its extremely low luminance value makes it difficult to perceive against most background colors, especially white or light shades. Using this color for text on a light background would result in very poor contrast, failing to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. #0F0034 falls far short of these recommendations. To improve accessibility, consider using this color sparingly and only for decorative elements or backgrounds where text is not required. When using it for text, pair it with a very light color such as #FFFFFF or a color with significantly higher luminance value to ensure sufficient contrast and readability for users, including those with visual impairments. Also consider increasing font sizes and weights to improve readability.
