What is color? Why do some of the things around us look red, some green, others blue?

Colors are really made by deflected (反射) light. We see color because most of the things reflect 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 of the light is reflected and some is taken in (吸引) and turned into (變成) heat (熱能).The darker the color is, the less light is reflected, the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.

1.When something reflects light, we can _____.

2.Something looks white because it reflects _____.

3.the dark-colored clothes are warm because ____ is taken in.

4.In summer ______ make people feel cool.

　　Colours are really made by reflected (反射) light. We see colour 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 and light, it is black.

　　Some of the light is reflected and some is taken in (吸收) and turned into (變成) heat (熱能). The darker the colour is, the less light is reflected, the more light is taken in. So dark-coloured (深色的) clothes are warmer in the sun than light-coloured clothes.
