General Information about #0B0B2A

The hexadecimal color code #0B0B2A represents a very dark shade of blue, often referred to as "Black Rock." In the RGB color model, it consists of 4.31% red, 4.31% green, and 16.47% blue. This color is primarily associated with depth, mystery, and sophistication. Due to its high blue component, it evokes feelings of calmness and stability, while its darkness adds a sense of formality and elegance. It's important to note that, while aesthetically pleasing, this color should be used with careful consideration, especially in contexts where readability and accessibility are crucial. Its low lightness value means it requires significant contrast when paired with text or other design elements to ensure they are easily visible.

The hex color #0B0B2A, also known as Black Rock, presents significant accessibility challenges, particularly in web design. Its extremely dark hue results in very low contrast against common background colors like white. This lack of contrast makes text and other elements difficult to read for users with visual impairments, including those with low vision or color blindness. According to WCAG guidelines, sufficient color contrast is essential for ensuring web content is accessible to everyone. To improve accessibility, it's crucial to pair #0B0B2A with much lighter colors, or to use it sparingly for decorative purposes where readability isn't critical. Tools for checking color contrast ratios can help designers ensure their color choices meet accessibility standards, promoting a more inclusive online experience.
