Cyan (#00FFFF) is a vibrant blue-green color that serves as one of the primary colors in the CMYK printing model. This electrifying hue combines equal parts green and blue light, creating a refreshing and energetic appearance that's instantly recognizable.

In digital design, cyan excels at drawing attention to key interface elements like buttons, links, and navigation items. Its cool tone promotes tranquility and mental clarity, making it ideal for productivity apps and wellness-focused websites. The color pairs beautifully with its complement red for high contrast, or with magenta and yellow for bold, modern schemes.

For more subtle designs, combine cyan with darker blue shades or neutral tones like gray and beige. However, avoid pairing it with warm yellows or muted colors that can clash with its vibrancy.

Cyan's association with tropical waters and clear skies makes it perfect for conveying freshness, innovation, and creativity. Tech companies often leverage this color to appeal to younger audiences and establish a cutting-edge brand identity.
