#0A0933

General Information about #0A0933

The hexadecimal color #0A0933, often referred to as "Black Rock," is a very dark shade of blue-leaning black. In the RGB color model, it is composed of 3.92% red, 3.53% green, and 20% blue. This unique combination results in a deep, mysterious hue. The color is often associated with sophistication, elegance, and depth. In terms of light and shadow, Black Rock sits very close to pure black, which gives it a strong presence when used in design. Its subtle blue undertones differentiate it from a true black, adding a touch of coolness. When using this color, it's crucial to consider its impact on readability and contrast, particularly in web design and user interfaces.

The hex color #0A0933, also known as Black Rock, presents significant accessibility challenges, primarily due to its very low luminance. This dark shade of blue-leaning black results in extremely poor contrast when used as text against a white background. Web Content Accessibility Guidelines (WCAG) require a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Black Rock fails to meet these standards, making it difficult for users, especially those with visual impairments, to read content displayed in this color. To improve accessibility, consider using lighter text colors, such as white or a very light gray, or implementing a background color that is significantly brighter. Tools like contrast checkers can help ensure compliance with accessibility standards, promoting inclusive design practices.
