What is color? Why do some of the things around us look red, some green, others blue?
Colors are really made by reflected(反射) light. We can see colors because most of the 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. If it doesn’t reflect any light, it is black.
Some light is reflected. But the other light is taken in and turns into heat. The darker the color is, the less light is reflected, and the more light is taken in. For this reason, dark-colored clothes are warmer in the sun than light-colored clothes.
【小題1】Colors are made by reflected light
