The color of Piezography Selenium inks were designed in reference to a silver fiber print that had been purposely short bath selenium-toned for Jon Cone by his teacher Arnald Gassan. This is the quintessential museum look ink set. While it prints with this perfect Selenium tone on Hahnemuhle Photo Rag paper, it will take on warmer and cooler tones on media that is warmer or cooler than Photo Rag.
