#172CCF

General Information about Persian Blue

Persian Blue, represented by the hex code #172CCF, is a deep, vibrant shade of blue that evokes feelings of royalty, sophistication, and tranquility. It is often associated with the color of the semi-precious stone lapis lazuli, which has been highly valued throughout history. In the RGB color model, Persian Blue is composed of 9.02% red, 17.65% green, and 81.18% blue. This high concentration of blue gives it its distinctive hue. The color is frequently used in art, design, and fashion to add a touch of elegance and depth. Its cool undertones make it a versatile choice for various applications, ranging from digital interfaces to interior decor, offering a sense of stability and trust when used effectively.

The color #172CCF, also known as Persian Blue, presents considerable accessibility challenges, especially concerning color contrast. When used as text against a white background, the contrast ratio is significantly low, failing to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (4.5:1) and large text (3:1). This means users with visual impairments may struggle to read content using this color. Similarly, using white text on a #172CCF background would also likely fail contrast checks. To improve accessibility, designers should pair #172CCF with much lighter shades for backgrounds when using dark text, or darker shades for text when using it as a background. Tools like contrast checkers can help determine compliant color combinations to ensure readability for all users, including those with low vision or color blindness. Thoughtful consideration of color pairings is crucial for inclusive design.
