General Information about Black Pearl

The hexadecimal color code #0A1B23 represents a very dark shade of blue, often referred to as Black Pearl. It is composed of 3.92% red, 10.59% green, and 13.73% blue. In the RGB color space, it is defined as rgb(10, 27, 35). This color is commonly perceived as a dark, muted, and somewhat mysterious hue. Its low saturation and brightness values contribute to its subtle and understated nature. Black Pearl evokes feelings of sophistication, elegance, and tranquility. It is frequently used in designs where a sense of depth and calmness is desired, making it suitable for backgrounds, accents, and various other applications. Its subtle appearance makes it versatile for many design projects.

The hex color #0A1B23, also known as Black Pearl, presents significant accessibility challenges, especially when used as a text color. Its low lightness value (approximately 5%) means it provides very little contrast against most background colors, including white. According to WCAG guidelines, sufficient contrast is essential for readability and usability, particularly for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Black Pearl is highly unlikely to meet these standards with lighter backgrounds. Therefore, when using this color, careful consideration must be given to the choice of foreground and background colors to ensure adequate contrast. Lighter shades of gray, or even pastel colors, might improve accessibility, but thorough testing with accessibility tools is crucial.
