Persian Blue has historical significance, often associated with royalty, spirituality, and sophistication. Its use dates back centuries, with evidence found in Persian art and architecture.

It's used in corporate branding, web design, and even interior decorating.

The hex color #1B38AF, also known as Persian Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value of 0.049 makes it difficult to achieve sufficient contrast against lighter backgrounds, potentially causing readability issues for text and other visual elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When used as a text color, #1B38AF requires a very light background to meet these standards. For example, pairing it with white (#FFFFFF) yields a contrast ratio of only 4.45:1, which is just barely compliant for normal text. Therefore, designers and developers should carefully consider the background color and text size when using #1B38AF to ensure accessibility for all users. Using a lighter tint of blue or a completely different color for text might be necessary to improve readability. It's also crucial to test the color combination with accessibility tools to verify compliance with WCAG guidelines.
