#140B2A

General Information about Black Rock

The hex color #140B2A, often referred to as 'Black Rock', is a very dark shade of blue-purple. It resides in the lower range of the color spectrum, possessing minimal brightness and a subtle hint of both blue and red undertones. In the RGB color model, it is composed of 8.63% red, 4.31% green, and 16.47% blue. This combination creates a color that evokes feelings of mystery, sophistication, and depth. Its primary use is often as a background or accent color where a dark, muted tone is desired. However, due to its darkness, care must be taken to ensure sufficient contrast with other elements, particularly text, to maintain readability and accessibility.

The hex color #140B2A, also known as Black Rock, presents significant accessibility challenges, especially in web design. Its low luminance value means that text rendered in this color on a white background, or vice versa, will likely fail WCAG contrast ratio guidelines. These guidelines are crucial for ensuring that content is perceivable by users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Black Rock falls far short, making it difficult for many users to read comfortably. To improve accessibility, consider using lighter tints or shades of the color or pairing it with a much lighter or darker color to meet contrast requirements. Tools are available online to check the contrast ratio between foreground and background colors, which can help designers make informed decisions.
