About Persian Blue

Persian Blue, with the hex code #251BCB, is a deep, rich shade of blue that evokes feelings of sophistication and tranquility. It is often associated with trust, loyalty, and intelligence. In color psychology, blue is known to have a calming effect and can promote relaxation and focus. This particular shade of blue is named after the historical association with Persian art and culture, where blue pigments derived from minerals like lapis lazuli were highly valued. Persian Blue can be used in a variety of design applications to convey a sense of stability and elegance. Its unique depth distinguishes it from brighter, more common blues.

The color #251BCB, also known as Persian Blue, presents accessibility challenges due to its relatively low luminance. When used as a background color, it requires light-colored text to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text, as per WCAG guidelines. For larger text (14pt bold or 18pt regular), a contrast ratio of 3:1 is acceptable. Insufficient contrast can make content difficult to perceive, especially for users with visual impairments. Using a color contrast checker tool can help determine if the chosen text and background color combination meets accessibility standards. Careful consideration of color combinations is essential to provide an inclusive and user-friendly experience.
