General Information about Persian Blue

Persian Blue, with the hexadecimal code #0D21BD, is a deep, vibrant shade of blue that evokes feelings of sophistication and tranquility. It is often associated with trust, intelligence, and stability. In color psychology, blue is known to promote calmness and relaxation, making it a popular choice for brands and designs that want to convey a sense of reliability and security. This particular shade of blue has a strong presence and can easily catch the eye, making it suitable for use in branding, marketing materials, and user interface design. Its deep hue also gives it a touch of elegance, making it a good choice for more formal applications.

The color #0D21BD, also known as Persian Blue, presents some accessibility challenges, especially when used as a background or text color. Its relatively low luminance contrast with lighter colors necessitates careful consideration. According to WCAG guidelines, sufficient contrast between foreground and background elements is crucial for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #0D21BD for text on a white background may not meet these guidelines, making it difficult for some users to read. To improve accessibility, consider pairing it with much lighter shades or using it sparingly for decorative elements. Additionally, providing alternative visual cues, like icons or labels, can enhance usability for users with color blindness.
