Abstract: A dichroic coating can be applied to a glass window of an electronic device to enhance the cosmetic and aesthetic appeal of the device. Different processes can be applied to the glass window in combination with a dichroic coating. For example, a layer of ink can be applied to the glass window in addition to one or more layers of dichroic material. The material layers can cover any suitable portion of the glass. For example, the material layers can include holes or openings. As another example, the material layers can be constructed from several distinct shapes placed on the glass. In some cases, software applications can be used to define a desired color profile for a coating, and to retrieve a suitable combination of dichroic and other layers to provide the desired color profile.
