#030036

General Information about #030036

The hexadecimal color code #030036 represents a very dark shade of blue-violet. It is composed of 1.18% red, 0% green, and 21.18% blue. In the RGB color model, it's defined as (3, 0, 54). This color falls into the range of very dark colors, almost approaching black. Due to its high blue component, it evokes feelings of calmness, sophistication, and depth. The near absence of red and green gives it a cool, somewhat somber tone. It is not a naturally occurring color, and its artificial nature makes it suitable for designs aiming for a modern or futuristic aesthetic. Its low luminance value limits its usability in contexts requiring high contrast or readability, especially against similar dark backgrounds.

The hex color #030036, often referred to as Black Rock, presents significant accessibility challenges. Its extremely low lightness value results in very poor contrast against typical light-colored backgrounds, such as white (#FFFFFF). According to WCAG (Web Content Accessibility Guidelines) standards, sufficient contrast is essential for users with visual impairments to perceive content effectively. Using #030036 for text or important user interface elements against a light background would likely fail accessibility tests. To improve accessibility, consider pairing it with a much lighter color to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Alternatively, using #030036 sparingly for decorative elements where legibility is not critical might be acceptable, but it should never be used where it affects usability or readability.
