General Information about Black Rock (#140133)

The hexadecimal color code #140133, often referred to as Black Rock, is a very dark shade of blue-purple. In the RGB color model, it is composed of 8.24% red, 0.39% green, and 20% blue. This combination results in a deep, muted color that evokes feelings of mystery, sophistication, and depth. The low saturation and luminance values contribute to its somber and grounding character. Hexadecimal colors are widely used in web design and graphic design for specifying colors precisely. Understanding the composition of a color like #140133 helps designers make informed decisions about color palettes and accessibility considerations.

The color #140133, also known as Black Rock, presents significant accessibility challenges, particularly in web design. Its very dark hue results in extremely low contrast against lighter backgrounds, making text and interface elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast is crucial for ensuring content is perceivable. To improve accessibility, avoid using #140133 for text or interactive elements on light backgrounds. If it must be used, pair it with a very light color such as white (#FFFFFF) or a pale yellow (#FFFFE0) to achieve a contrast ratio that meets WCAG AA or AAA standards. Tools like contrast checkers can help evaluate the contrast ratio and ensure compliance. Consider offering alternative color themes to allow users to customize the display according to their needs and preferences. Using this color for decorative purposes with no informational value has no accessibility implications. When using this color, verify that any images have sufficient alternative text.
