Why do some of the things around us look red, some green, others blue? Colors are really made by reflected(反射) light. We see colors because most of things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. Some of the light is reflected and some is taken in (吸收) and turned into heat(热能). The darker the color is, the less light is reflected, and the more light is taken in.
