The photos of the glass on this web site are as close as possible.  Due to camera and monitor displays the color maybe slightly different once you receive them. 

Characteristics - Color saturation varies depending on application.  Thin layers may be lighter and thick layers darker and more saturated.  Some colors are "strikers" which may appear pale or even colorless in their cold form but "strike" or mature to target color when fired.
