Black Russian

#04001B

General Information about #04001B

#04001B, also known as Black Russian, is an extremely dark shade of blue-black. In the RGB color model, it consists of 4/255 red (1.57%), 0/255 green (0%), and 27/255 blue (10.59%). This color is often associated with sophistication, mystery, and elegance. Its near-black appearance makes it suitable for applications where a subtle alternative to pure black is desired. Due to its low luminance, it is often used as a background color or in designs where a calming or subdued effect is intended. It's important to consider contrast ratios when using this color for text or important visual elements to ensure accessibility.

The hex color #04001B, a very dark shade of blue-black, presents significant accessibility challenges, particularly in text applications. Its extremely low luminance results in very poor contrast against most background colors, especially white. 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 ensure readability. This dark hue will likely fail these contrast tests against lighter backgrounds, making it difficult for users, especially those with visual impairments, to discern text or important visual elements. To enhance accessibility, it's crucial to pair #04001B with much lighter colors, conduct thorough contrast ratio checks, and potentially use it sparingly for decorative purposes rather than essential information delivery.
