There are many colours in nature. But do
you think that colour has weight? I think you'll say "No". But I'm afraid
you are wrong. If you don't believe it, you may do a small experiment(实验).
First, put two objects with the same weight
into two boxes. Then cover the boxes.
Then,
rap(包裹) one box with a red piece of paper, the other one with a white
piece of paper. OK. Now hold the boxes with your hand one by one. It is certain
that you will think the red one is a little heavier.
Why
do you think so? A scientist found that different colours have different
weights in man's mind. That is to say, every colour has its own weight in our mind.
The
scientist told us that colours also have smell. Can you smell the colour? Of
course not. Then why did the scientist say so. That is because every colour
stands for(代表) a kind of light with a certain
wavelength(波长). It reaches our brain through sense
organs.
According to this discovery, scientists say that people accept the
colours-they like, and refuse the colours they hate. So your body and mind will
be healthy by using the colours you like. Or you'll be nervous or even get ill.
For example, you 'like blue and hate red. If you stay in a room with red
windows, wallpaper and furniture(家具) for two
hours, you'll feel you have been there for four hours, you'll fed you have been
there for four hours. But if the room is blue, you'I1 feel you have been there
for only an hour. And, if a person walks out of a blue room and into a red
room, his temperature will rise.
That
means our body temperature will change with different colours.
