Black Rock

#030531

General Information about #030531

The hexadecimal color code #030531 represents a very dark shade of blue, often referred to as Black Rock. It is composed of 1.18% red, 1.96% green, and 19.22% blue. In the RGB (red, green, blue) color model, this color is created by combining very small amounts of red and green with a more significant amount of blue. This imbalance results in the deep, almost black appearance with a subtle blue undertone. The color is often associated with sophistication and mystery. Colors like this are often used as a background color in websites to create a strong contrast with the text and other elements. Due to the darkness of this color, it is necessary to combine it with lighter and brighter shades.

The color #030531, also known as Black Rock, presents significant accessibility challenges, particularly in text-based applications. Due to its extremely low luminance, it offers very poor contrast against typical light backgrounds. This fails to meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast, making it difficult for users with visual impairments to read text or distinguish interface elements. To improve accessibility, consider pairing this color with very light shades like white or bright yellows to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid using #030531 for critical interactive elements or informational graphics without careful consideration of its impact on users with low vision or color blindness. Thoroughly test color combinations to ensure usability for all users.
