These can be individually mounted to a building or for easier installation, often each individual letter is mounted to a raceway, which is then installed as one piece to the building front. When using a raceway it often painted to match the buildings exterior. This color matching will tend to make the raceway quite subtle causing it to go unnoticed. In the case of a brick or textured building a digit photo of the surface can be transfored into a digital print. This print is then applied to the raceway. Again the raceway will tend to disappear. Channel Letters are usually illuminated but are available in a non-illuminated version as well.
