10 years ago, Mikkel Carl started working with titanium. Based on a technique called anodizing, he creates vivid, colorful paintings entirely without the use of pigment. By running an electrical current through the metal plate, an invisible pattern of microscopic crystals is formed, which refracts the light in the color spectrum of the rainbow. More specifically any number of volts between 0 and 110 has a color. For instance, 15 volts is purple, 25 volts is blue, 40 volts is yellow, and 75 volts is pink.

Using car battery acid, said current is directed onto the titanium plate using a series of painterly techniques developed by the artist over the years.

In the middle of the room, a rotating disk seemingly made from banged-up chrome steel with greasy fingers, soldering and all, enables you to see yourself and others contemplate the paintings.
