The Faber-Castell Polychromos Peacock Blue colored pencil (ref. 110153) recreates the rich blue-green hue of peacock feathers in a soft, water-insoluble 3.8 mm lead. Its fluid texture makes it easy to create color gradients with the blues and greens of the Polychromos line. The Peacock Blue shade is perfect for illustrations of nature, exotic plumage, and decorative elements with great visual impact.
