Black Rock

#000030

General Information about #000030

The hex color #000030, often referred to as "Black Rock," is a very dark shade of blue. In the RGB color model, it consists of 0% red, 0% green, and 18.8% blue. This composition results in a color that is perceived as deeply muted and almost black to the human eye. Due to its low luminance, #000030 is frequently used to create a sense of depth, mystery, or sophistication in design projects. However, its limited brightness requires careful consideration to ensure readability and accessibility when used for text or interactive elements. It's important to remember that #000030 is at the very edge of visibility for many people and should therefore be paired with brighter colours to have the most impact.

The hex color #000030, also known as Black Rock, presents significant accessibility challenges. Its extremely low luminance makes it difficult to discern against most backgrounds, particularly white or light-colored ones. For web content, this severely impacts readability for users with visual impairments, including those with low vision or color blindness. According to WCAG guidelines, sufficient contrast is essential for text and interactive elements. Using #000030 for text on a light background would fail these contrast tests. To improve accessibility, consider using lighter shades or pairing #000030 with a much lighter accent color. Furthermore, avoid using it as the sole indicator for interactive elements, such as links or buttons; provide additional cues like underlines or icons.
