About Persian Blue

Persian Blue, with the hexadecimal code #0B21BF, is a deep and intense shade of blue. It belongs to the blue color family and is characterized by its strong saturation and relatively low brightness. This color evokes feelings of calmness, depth, and sophistication. In color theory, Persian Blue is considered a cool color, making it suitable for designs aiming to project a sense of stability, trust, or intelligence. Due to its low luminance, it is best used sparingly or in combination with lighter colors to ensure readability and visual comfort. It is often associated with royalty and elegance, thus can be used in logos or branding where trust and professionalism are required.

The color #0B21BF, also known as Persian Blue, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 5% results in poor contrast against typical light backgrounds like white or light gray. This low contrast makes text and graphical elements difficult to perceive, potentially causing eye strain and hindering readability. To improve accessibility, it is strongly recommended to pair this color with significantly lighter hues, ensuring a contrast ratio that meets WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is advisable. Consider using a color contrast checker tool to verify compliance. Furthermore, avoid using #0B21BF as the sole means of conveying information; supplement it with textual cues or alternative visual indicators to ensure inclusivity for all users.
