Black Rock

#05062E

General Information

The hex color #05062E, often referred to as "Black Rock," is a very dark shade of blue, almost appearing black to the naked eye. It resides at the lower end of the luminance scale, characterized by minimal brightness and high saturation for its limited visible spectrum. In the RGB color model, it is composed of 2% red, 2.4% green, and 18.4% blue. This composition explains the subtle bluish undertone that distinguishes it from pure black. Colors like #05062E are typically used to create a sense of depth, mystery, or sophistication in design. Due to its low lightness value, it is not appropriate for text or important user interface elements without sufficient contrast.

The hex color #05062E, also known as Black Rock, presents significant accessibility challenges due to its extremely low luminance. The contrast ratio against a standard white background is critically low, making text or interactive elements rendered in this color nearly invisible to users with normal vision. This issue is severely exacerbated for individuals with visual impairments, including those with low vision or color blindness. To ensure inclusivity, it is crucial to avoid using #05062E for text, icons, or other essential visual components unless paired with a very light color that provides a high contrast ratio (ideally exceeding the WCAG AA or AAA guidelines). Consider alternative, lighter shades or incorporating contrast-enhancing techniques like borders or background shapes to improve visibility and meet accessibility standards. Proper color choices are important for accessible design.
