General Information about Black Pearl (#05172B)

The hex color #05172B, commonly known as Black Pearl, is a very dark shade of blue, almost black. In the RGB color model, it is composed of 2.0% red, 9.0% green, and 17.3% blue. This composition places it within the cool color spectrum. Its primary attribute is its depth, offering a sense of mystery and sophistication. In terms of color theory, Black Pearl can be used to create contrast with brighter, warmer colors, making those elements stand out. Due to its low lightness value, it should be used carefully in design to avoid readability issues, especially when used as a background. Its subtle blue undertones differentiate it from pure black, adding a unique visual interest. Black Pearl is often associated with elegance, luxury, and modernity, making it a popular choice in various design applications.

The hex color #05172B, also known as Black Pearl, presents significant accessibility challenges, especially in web design. Due to its very dark nature, using this color as a primary background necessitates extremely light text to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA standards. Black Pearl, being so close to black, typically fails to meet these ratios with most common text colors. Therefore, it's crucial to carefully evaluate color combinations using contrast checkers and consider its impact on users with visual impairments. Overuse of #05172B without proper contrast adjustment can lead to a poor user experience, making content difficult to read and navigate.
