The color is often referred to as Jackson's Purple. Its dark nature means it has a low luminance value, making it suitable for backgrounds or accents where contrast is desired against lighter elements. This deep, saturated color can evoke feelings of creativity, mystery, and sophistication. In terms of color theory, it lies closer to blue than to red on the color spectrum. The CMYK representation of #111B87 is (87, 80, 0, 47), indicating the percentages of cyan, magenta, yellow, and black inks needed to reproduce the color in print media.

The hex color #111B87, also known as Jackson's Purple, presents significant accessibility challenges, particularly in text-based contexts. Its low luminance value results in a poor contrast ratio against common background colors like white. 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 visual impairments. Using #111B87 for text on a white background falls far short of these recommendations. To improve accessibility, consider using lighter shades of purple or pairing it with a significantly lighter foreground color. When using this color for decorative elements, ensure that the surrounding content provides sufficient contrast. For interactive elements, provide clear visual cues beyond color to ensure users can perceive the function and state of the element. Thorough testing with accessibility evaluation tools is crucial to validate that the color choices meet accessibility standards and provide a usable experience for all users, including those with color vision deficiencies.
