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 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 (变成) heat (热能).  The

warmer in the sun than light-colored clothes.
