General Information about Black Rock

The hexadecimal color #090034, also known as Black Rock, is a very dark shade of blue. It is composed of 3.53% red, 0% green, and 20.39% blue. In the RGB color model, it is represented as rgb(9, 0, 52). This color is primarily used to evoke feelings of depth, mystery, and sophistication. Due to its low luminance value, it's important to consider its impact on accessibility when using it in design. It falls into the cool color temperature category because of the blue pigment. Black Rock can be effectively used to create contrast when combined with lighter, warmer colors to make the interface more compelling.

The hex color #090034, often referred to as Black Rock, presents significant accessibility challenges due to its extremely low luminance. When used as text against a white background, it fails all WCAG (Web Content Accessibility Guidelines) contrast ratio requirements. This means individuals with visual impairments, including those with low vision or color blindness, would struggle to read content displayed in this color. Similarly, using white text on a #090034 background would also pose readability issues. To ensure accessibility, it's crucial to avoid using this color for text or essential interface elements. If it is used as a background, very light foreground colors are a must-have. Consider lighter alternatives or implement sufficient contrast ratios (at least 4.5:1 for normal text and 3:1 for large text) by adjusting the color or using supplementary visual cues.
