General Information about Black Pearl

The hex color code #001721, often referred to as Black Pearl, is a very dark shade of blue-black. It is composed of 0% red, 8.2% green, and 12.9% blue. In the RGB color model, it is represented as (0, 23, 33). This color has a very low intensity and is primarily used for backgrounds or accents where a deep, dark color is desired. Due to its low luminance, careful consideration must be given to contrast ratios when using it with text or other visual elements. In a CMYK color space, the values are C:100, M:30, Y:0, K:87, meaning it requires a high amount of cyan to achieve this dark hue.

The hex color #001721, also known as Black Pearl, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value necessitates careful consideration of contrast ratios. When used as a background color, text displayed on top must be very light, ideally white or a very pale shade of yellow, to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using tools to verify contrast ratios is crucial. Additionally, avoid using this color for crucial interactive elements or links without providing strong visual cues, such as underlines or borders, to help users easily identify them. Also consider providing alternative high contrast themes.
