General Information about #0B002E

The hex color #0B002E, often referred to as "Black Rock", is a very dark shade of purple, almost appearing black to the naked eye. It belongs to the family of purple colors, but its extremely low brightness and saturation give it a unique character. In the RGB color model, it is composed of 4.31% red, 0% green, and 18.43% blue. This color is generally perceived as mysterious, sophisticated, and even melancholic. Its dark nature makes it less suitable for applications requiring high visibility, such as safety signs or critical user interface elements. However, it can be used to create a sense of depth, mystery and elegance in designs. This hex color is very similar to black. This color is not often used in designs for the general public.

The hex color #0B002E, also known as Black Rock, presents significant accessibility challenges, especially in web design. Its extremely low luminance makes it difficult to distinguish from black, requiring careful consideration of contrast ratios. According to WCAG guidelines, sufficient contrast between text and background is crucial for readability, particularly for users with visual impairments. When using #0B002E for text, it's essential to pair it with a very light color to ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Using this color for interactive elements like buttons or links also necessitates clear visual cues beyond color alone, such as underlines or icons, to ensure usability for all users. Avoid using this color as a background in websites that are meant for the general public.
