General Information about #15052F

The hex color #15052F, often referred to as "Black Rock," is a deep, dark shade of purple. It resides within the blue-violet spectrum of the color palette, possessing minimal brightness and high saturation for its luminance level. In color theory, #15052F evokes feelings of sophistication, mystery, and depth. Due to its darkness, it is rarely used as a primary color in design but can be effective as an accent or background element when paired with lighter, contrasting colors. Its hexadecimal representation signifies that it is composed of 8.24% red, 1.96% green, and 18.43% blue. This color is not commonly found in nature but is often synthesized and utilized in digital arts, fashion, and interior design to achieve a particular aesthetic.

The hex color #15052F, also known as Black Rock, presents significant accessibility challenges. Its very low luminance value (approximately 0.006) means that text rendered in this color against a white background, or vice versa, will fail WCAG (Web Content Accessibility Guidelines) contrast ratio requirements by a considerable margin. To ensure readability and usability for users with visual impairments, it is crucial to avoid using #15052F for text or interactive elements without a very light, contrasting background. Foreground elements should be carefully tested with accessibility tools to meet the minimum contrast ratios of 4.5:1 for normal text and 3:1 for large text, according to WCAG 2.1 standards. Consider alternative, lighter color options or employing color contrast checkers during design to comply with accessibility guidelines.
