General Information about Black Pearl (#031728)

The hex color #031728, also known as Black Pearl, is a very dark shade of blue-black, almost appearing as pure black to the naked eye. In the RGB color model, it consists of 3 parts red, 23 parts green, and 40 parts blue. Its darkness is characterized by very low saturation and luminance values. This color is often associated with sophistication, elegance, and mystery, and it lends a sense of depth to designs. Due to its deep tone, it's crucial to use it carefully in combination with lighter colors to ensure readability and visual balance. Black Pearl can evoke a sense of luxury and can be utilized to create sleek and modern designs, particularly in the tech and fashion industries.

The hex color #031728, also known as Black Pearl, presents significant accessibility challenges. Its very low luminance value means that text rendered in this color requires extremely light foreground colors to meet WCAG (Web Content Accessibility Guidelines) contrast requirements. For body text, achieving a contrast ratio of 4.5:1 is essential for Level AA compliance, and a ratio of 7:1 is recommended for Level AAA. Larger text (14pt bold or 18pt regular) needs a minimum ratio of 3:1. Due to its darkness, this color is best used sparingly for decorative elements or backgrounds where no text is present. When text is necessary, prioritize light shades of yellow (#FFFF00), white (#FFFFFF), or very light grays to ensure readability for users with visual impairments. Careful consideration and testing with accessibility tools are crucial to avoid creating barriers for users.
