#00001B

General Information about #00001B

The color #00001B, also known as Black Russian, is an extremely dark shade of blue. It is composed of 0 red, 0 green, and 27 blue, represented in the RGB color model. In the hexadecimal color system, it is denoted as #00001B. Due to its very low luminance, this color is often perceived as nearly black. Black Russian is rarely used as a primary color in design because of its darkness, but it can be employed as a subtle accent or background element when a deep, understated tone is desired. When using this color, it's essential to ensure adequate contrast with surrounding elements to maintain readability and accessibility, especially for text and interactive components. Its dark nature makes it suitable for creating a sense of depth, mystery, or sophistication in design projects.

The hex color #00001B presents significant accessibility challenges, primarily due to its extremely low luminance. This dark shade of blue renders text and interface elements nearly invisible when used against a black or similarly dark background. To ensure usability for all users, including those with visual impairments, it is crucial to use #00001B with a sufficiently light foreground color that provides a high contrast ratio. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as specified by WCAG guidelines. Proper color contrast enhances readability and reduces eye strain, making web content more accessible to a wider audience. Tools for checking color contrast are widely available and should be integrated into the design and development process to ensure compliance with accessibility standards.
