General Information about Persian Blue

Persian Blue, identified by the hex code #172ACF, is a deep, vibrant shade of blue known for its richness and intensity. It evokes feelings of royalty, sophistication, and depth, often associated with the precious lapis lazuli stone from which it historically derived its color. In the RGB color model, Persian Blue is composed of 9.02% red, 16.47% green, and 81.18% blue. This combination results in a color that is both striking and calming, making it a popular choice in various design fields. The color name is rooted in the historic use of Lapis Lazuli in the Persian empire and its associated art and decoration. It stands out as a unique hue within the blue color family, offering a distinct alternative to more common shades like navy or sky blue.

The hex color #172ACF, also known as Persian Blue, presents some accessibility challenges, particularly when used as a text color. Its relatively low luminance contrast against a white background means that users with visual impairments may find it difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text, and 3:1 for large text. Persian Blue may not meet these requirements, necessitating careful consideration of its use. To enhance accessibility, consider pairing it with a very light color for the background, or using it sparingly for decorative elements rather than critical text. Tools like contrast checkers can accurately measure the contrast ratio between text and background colors to ensure compliance with accessibility standards.
