General Information about Persian Blue

Persian Blue, represented by the hexadecimal color code #133DD3, is a vibrant and captivating shade of blue. It evokes feelings of tranquility, depth, and sophistication. In the RGB color model, it's composed of 7.45% red, 23.92% green, and 82.75% blue. This color is often associated with royalty, intelligence, and stability. It is a popular choice in various design fields, including web design, graphic design, and interior decoration, due to its ability to add a touch of elegance and visual interest. However, its relatively low luminance means that it requires careful consideration of contrast ratios to ensure accessibility, especially when used for text or interactive elements.

The color #133DD3, also known as Persian Blue, presents some accessibility challenges, particularly concerning color contrast. When used as text on a white background, the contrast ratio is insufficient to meet WCAG (Web Content Accessibility Guidelines) requirements for normal text (AA level). This means that users with moderate visual impairments may find it difficult to read. To improve accessibility, consider using a lighter background color or darkening the text color. For example, pairing it with a very light yellow or white could improve readability. Also, avoid using this color for critical information or interactive elements without careful consideration of contrast. Providing alternative visual cues, like icons or text labels, can further enhance usability for all users, including those with color vision deficiencies.
