#00042E

General Information about #00042E

The hex color #00042E, often referred to as Black Rock, is a very dark shade of blue. In the RGB color model, it is composed of 0% red, 1.57% green, and 18.43% blue. This composition results in a color that is perceived as nearly black but with a subtle blue undertone. The color's visual impact is characterized by its depth and darkness, making it suitable for creating a sense of mystery, sophistication, or depth. It is frequently used in design applications where a dark, grounding color is needed, providing a subtle alternative to pure black.

The color #00042E, also known as Black Rock, presents significant accessibility challenges, especially in text-based contexts. Its extremely low luminance value makes it nearly invisible against most backgrounds, including the standard white background used on many websites. According to WCAG guidelines, this color fails all levels of contrast requirements for normal text, large text, and user interface components. To ensure accessibility, it is essential to avoid using #00042E for text or interactive elements without a very light background color to provide sufficient contrast. Using tools to check color contrast ratios is crucial for making web content accessible to users with visual impairments. A minimum contrast ratio of 4.5:1 is recommended for standard text and 3:1 for large text.
