Black Rock

#12072D

General Information

#12072D, also known as Black Rock, is a very dark, desaturated shade of purple. In the RGB color model, it is composed of 7.1% red, 2.7% green, and 17.6% blue. Its hexadecimal representation is #12072D. This color leans towards the darker end of the spectrum, making it a challenging choice for situations requiring high contrast. The human eye perceives it as a deep, muted tone, often associated with sophistication and mystery. Its low saturation means that it lacks vibrancy, contributing to its somber and subdued character. Understanding its composition and perceptual qualities is essential for designers seeking to leverage its unique attributes effectively.

The hex color #12072D presents significant accessibility challenges, primarily due to its very low luminance. This deep, dark shade of purple provides insufficient contrast when paired with lighter text or interface elements, making it difficult for users with visual impairments to discern content. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. #12072D falls far short of these recommendations when used as a background or text color against common lighter colors like white or yellow. To improve accessibility, consider using a much lighter color for text or interactive elements when #12072D is the background. Another strategy is to use #12072D sparingly, opting for it as an accent color rather than a primary background or text color. Careful consideration of color combinations and contrast ratios is crucial to ensure that digital content is usable and inclusive for all users.
