General Information about Black Pearl

The hexadecimal color code #05171E represents a very dark shade of blue-gray, often described as Black Pearl. It resides in the range of near-black colors, possessing minimal luminance and high darkness. In the RGB color model, it is composed of 2% red, 9% green, and 12% blue. The color is often associated with elegance, sophistication, and a sense of mystery. Due to its low brightness, it is frequently used to convey a subdued and calming atmosphere. Black Pearl is often used in visual design, graphic arts, and fashion to create a high-end effect and is used to add depth and elegance to designs. The color leans toward the cooler side of the spectrum because of its blue undertones.

The color #05171E, also known as Black Pearl, presents significant accessibility challenges, especially in text-based contexts. Its very low luminance value of approximately 0.003 makes it exceedingly difficult to achieve sufficient contrast against lighter backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with moderate visual impairments. Black Pearl struggles to meet these ratios with most commonly used background colors. Web developers should exercise extreme caution when using this color for text or interactive elements. If used, a very light color should be used as text. Thorough testing with accessibility tools is crucial to validate that sufficient contrast is achieved to avoid usability issues for users with low vision or color blindness. Due to these limitations, it is advisable to use this color sparingly and prioritize alternative color palettes that offer better contrast ratios for improved accessibility.
