Dichroic glass is simply beautiful. Often referred to as dichro or dicro, the term refers to multiple ultra-thin microlayers of metal oxides which are evaporated onto the surface of glass in a vacuum chamber. These oxides change the way that light is transmitted and reflected, so that as you turn the glass, the color changes. A dichroic coating appears to have additional colors when you turn it and view it from different angles. A piece of dichroic glass may appear one color when you look at it straight on, but different colors when viewed from the side or at an angle. The exciting news is that glass is not the only material that can be coated with dichroic material — paper can be coated with dichroic material as well.
