General Information about Persian Blue

The hex color #1538B5, also known as Persian Blue, is a deep and vibrant shade of blue with a strong presence. In the RGB color model, it is composed of 8.24% red, 21.96% green, and 70.98% blue. This specific combination results in a color that is often associated with royalty, wisdom, and stability. Persian Blue has a rich history, dating back to ancient Persia where it was used in ceramics, textiles, and decorative arts. Its unique hue is due to the presence of the pigment ultramarine, which was originally derived from the mineral lapis lazuli. Today, Persian Blue is widely used in graphic design, web development, and other creative fields to evoke a sense of elegance and sophistication. Its distinct character makes it a versatile choice for various applications, from branding to art.

The color #1538B5, also known as Persian Blue, presents some accessibility challenges due to its relatively low luminance. When used as a foreground color on a white background, or vice versa, the contrast ratio may not meet the WCAG (Web Content Accessibility Guidelines) requirements for level AA or AAA compliance. This means that users with visual impairments, such as those with low vision or color blindness, may find it difficult to read text or distinguish elements using this color. To improve accessibility, consider using a lighter shade of blue for backgrounds and a darker color like white or a very light grey for foreground elements. Alternatively, pairing Persian Blue with a high-contrast color like yellow or white can enhance readability and ensure a better user experience for all users, including those with disabilities. Testing the color combination with accessibility tools is crucial to verify compliance and ensure inclusivity.
