General Information about Persian Blue

The color #0B42DB, commonly known as Persian Blue, is a deep and vibrant shade of blue with a rich history and cultural significance. It sits within the blue color spectrum, leaning towards the more intense and saturated end. In terms of color theory, it's a primary color derivative, meaning it can be created by mixing cyan and a touch of magenta. This particular shade evokes feelings of trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven. Blue is considered beneficial to the mind and body. It slows human metabolism and produces a calming effect. Persian Blue, with its depth and intensity, carries these attributes even further. The hexadecimal code #0B42DB precisely defines the color's composition, making it easily reproducible in digital design and various applications. Its use dates back centuries, with ties to royalty and prestige.

The color #0B42DB, also known as Persian Blue, presents some accessibility challenges, particularly when used as text on a white background. Its relatively low luminance results in a contrast ratio that may not meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast. For instance, using this color for body text would likely require a larger font size (at least 18pt or 14pt bold) to ensure readability for users with low vision or color blindness. Developers should consider pairing it with a very light background color, like white (#FFFFFF) or a light grey (#F0F0F0), to improve contrast. Alternatively, when designing user interface elements, it's advisable to use this color sparingly, reserving it for decorative accents or interactive elements that don't rely solely on color to convey information. Providing additional visual cues, such as icons or labels, can further enhance accessibility. Thorough testing with accessibility tools and real users is essential to validate the color's usability across different scenarios and user needs. Using online contrast checkers can also help to identify compliant and accessible color pairings.
