#190034

General Information about #190034

The hex color code #190034, often referred to as "Black Rock", represents a very dark shade of purple in the RGB color model. It is composed of 9.8% red, 0% green, and 20.4% blue. In the CMYK color model, it consists of 52% cyan, 100% magenta, 0% yellow, and 80% black. This color is typically perceived as a deep, somber, and somewhat mysterious hue. Due to its high black concentration, it is a very dark color and should be used judiciously in design. Understanding the color composition in both RGB and CMYK models is crucial for designers to accurately reproduce the color across various media, from digital screens to printed materials. Its inherent darkness makes it a difficult color to use effectively, as it tends to absorb light and requires careful consideration of surrounding colors and lighting conditions.

The hex color #190034, also known as Black Rock, presents significant accessibility challenges. Its very dark nature results in extremely low contrast against light backgrounds, making text and graphical elements difficult to discern for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color likely fails to meet these criteria when paired with common background colors like white or light gray. Web developers should avoid using #190034 for text or important UI elements unless paired with a very light color that provides sufficient contrast. Tools like contrast checkers can accurately measure the contrast ratio between #190034 and a chosen background color, ensuring compliance with accessibility standards and creating a more inclusive user experience. In cases where this color is crucial for branding, consider using it sparingly for decorative elements or employing color combinations that meet accessibility requirements.
