The emissive color element serves to set the intrinsic emission of an active object. The emission is an additional object color component, which is added to the resulting total color of the object. It is independent of the environment lighting. The emissive color of an object can be set by the color constant or compound color components to color elements. The emission of an object does not provide any lighting of neighboring objects, being an additional object color component only. Another option for the basic lighting of an object is ambient light.
