It is defined by its rich saturation and strong presence, evoking feelings of depth, sophistication, and creativity. In color psychology, blue is often associated with trust, stability, and intelligence. Persian Blue specifically carries a sense of regality and luxury, reminiscent of the historical use of lapis lazuli in Persian art and jewelry. This color can be used to evoke feelings of calmness and serenity, but also a sense of power and importance. It is a popular color for branding, design, and artistic expressions. Its hex code is a representation of a specific point in the RGB (Red, Green, Blue) color space, where the intensity of each primary color component is uniquely defined.

The hex color #211bcb, also known as Persian Blue, presents some accessibility challenges, particularly in text applications. Its relatively low luminance necessitates careful consideration of contrast ratios. When used as a text color, it requires pairing with very light backgrounds to meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. If the background is not light enough, users with visual impairments may find it difficult to read. Conversely, when used as a background color, #211bcb requires very light text to ensure readability. The color's deepness may cause eye strain if not balanced with adequate contrast. Ensure thorough testing with accessibility tools and real users to validate the color combination's usability.
