General Information about Persian Blue

The color #1F1BCB, commonly known as Persian Blue, is a deep, vibrant shade of blue that evokes a sense of royalty, depth, and sophistication. It's located in the blue-violet segment of the color spectrum, exhibiting a strong blue hue with a slight hint of purple. In the RGB (Red, Green, Blue) color model, it is composed of 12.2% red, 10.6% green, and 79.6% blue. Persian Blue has historical significance, often associated with the precious mineral lapis lazuli, which has been used in art and decoration for centuries. Its hexadecimal value, #1F1BCB, is a specific code that represents this color in digital contexts, widely used in web design, graphic design, and other digital media. This color tends to create feelings of trust, intelligence, and stability, and is often chosen by companies looking to project those traits. It's important to use this color carefully as it can also be perceived as cold and aloof if overused.

The hex color #1F1BCB, also known as Persian Blue, presents significant accessibility challenges, especially when used as a primary color for text or interactive elements. Its low luminance value of approximately 0.10 means it offers very little contrast against standard light backgrounds like white (#FFFFFF). According to WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14pt bold or 18pt regular). Using #1F1BCB on a white background results in a contrast ratio far below these recommendations, making it difficult for users with visual impairments, including those with low vision or color blindness, to read the content. To improve accessibility, it is essential to pair #1F1BCB with much lighter colors or use it sparingly for purely decorative purposes where readability is not a concern. Considering alternative color combinations or employing tools to evaluate contrast ratios is crucial for ensuring an inclusive user experience. This color is more suitable for graphical elements where exact readability is not critical.
