General Information about Black Pearl

The color #0A1121, also known as Black Pearl, is a very dark shade of blue-black. It belongs to the family of near-black colors and possesses a unique visual characteristic that sets it apart. Its hexadecimal value, #0A1121, indicates its composition in the RGB (Red, Green, Blue) color model, where each pair of characters represents the intensity of the corresponding color channel. In this case, '0A' represents the red channel, '11' represents the green channel, and '21' represents the blue channel. All three values are relatively low, contributing to the color's overall darkness. Black Pearl conveys a sense of sophistication, mystery, and depth. It is often used in design to evoke feelings of elegance, modernity, and understated luxury. Its subtle blue undertones add a touch of refinement, distinguishing it from pure black.

The hex color #0A1121, also known as Black Pearl, presents significant accessibility challenges, particularly in text and user interface design. Its extremely low luminance results in very poor contrast against virtually all but the lightest backgrounds. According to WCAG guidelines, sufficient contrast is crucial for readability and usability, especially for users with visual impairments. To ensure accessibility, using #0A1121 for text requires a background color of nearly pure white or a very light tint. However, even with a light background, careful consideration must be given to font size and weight, as thin or small fonts may still be difficult to discern. It is advisable to use contrast checking tools to verify compliance with accessibility standards. In interface design, avoid using #0A1121 for essential interactive elements without providing alternative visual cues such as outlines, borders, or icons. The lack of contrast can make it nearly invisible to some users, severely hindering their ability to navigate and use the site effectively. Alternative colors with higher luminance should be explored to ensure inclusive design.
