General Information about #150232

#150232, also known as Black Rock, is a very dark shade of purple that evokes feelings of mystery, sophistication, and depth. It's a color that sits between black and purple, leaning heavily towards the darker end of the spectrum. This color is created by combining small amounts of red and blue, resulting in a hue that is both calming and intriguing. Its RGB values are R:21, G:2, B:50. Due to its very low luminance, #150232 is generally not a good choice for text on its own, especially against a dark background, as it lacks sufficient contrast. The color can be used to evoke feelings of luxury, and high-quality and is often used in design to create a sense of elegant design and mystery. Black Rock is often used in branding and design to communicate a sense of sophistication and exclusivity.

The hex color #150232, also known as Black Rock, presents significant accessibility challenges, primarily due to its low luminance. With such a dark hue, achieving sufficient contrast against white or lighter backgrounds is critical to ensure readability and usability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet AA compliance. When using #150232 for text or interactive elements, careful consideration must be given to the foreground color selection. Light shades of yellow, white, or even lighter grays are better options to provide appropriate contrast. Tools like contrast checkers can be invaluable in determining if a color combination meets accessibility standards. Furthermore, avoid using #150232 for essential visual information without providing alternative cues, such as labels or icons, as users with low vision may struggle to differentiate it from other dark elements.
