#000130

General Information about Black Rock

The hexadecimal color code #000130, also known as Black Rock, represents a very dark shade of blue. It is composed of 0% red, 0.39% green, and 19.61% blue. In the RGB color space, it has the numerical values of 0, 1, and 48 respectively. Its primary attribute is its extremely low luminance, rendering it near black. This color is not commonly found in nature but can be associated with the deep sea or a night sky. In color theory, it is considered a tertiary color, derived from mixing primary and secondary colors. The color's darkness provides a sense of depth and mystery, often associated with concepts of the unknown or the profound. Due to its intense darkness, it needs to be used with extreme care when used for design projects.

The color #000130, also known as Black Rock, presents significant accessibility challenges. Its extremely low lightness value results in very poor contrast against almost any background color, especially white (#FFFFFF). This makes text or interactive elements using this color nearly impossible to read for users with visual impairments, including those with low vision or color blindness. Adhering to WCAG (Web Content Accessibility Guidelines) is crucial. To meet WCAG standards, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text. Black Rock falls far short of these requirements when paired with typical background colors. Therefore, it is strongly advised against using #000130 for text, icons, or interactive elements without careful consideration of contrast. Alternatives such as lighter shades of gray or other colors with significantly higher luminance should be preferred to ensure readability and accessibility for all users. Proper color choices enhance the usability and inclusivity of digital content.
