About ten men in every hundred have the trouble of colorblindness in some way. Women are luckier, only about five in every hundred are affected in this matter. Perhaps, after all, it is safer to be driven by a woman.

There are different shapes of color blindness. For example, a man may be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can not tell the difference between blue and green. Only a few unlucky men may see everything in shades of green-a strange world indeed.

Colour blindness in human beings is a strange thing to say clearly. In only one eye there are millions of very small things called “cones^①”. These help us to see in a bright light and to tell difference between colours. There are also millions of “rods^②”，but these are used for seeing when it is nearly dark. They show us shapes but no colours. Some insects have favourite colours. Mosquitoes^③ like blue but do not like yellow. A red light will not attract insects, but a blue light will. Human beings also have favourite colours. Yet we are lucky. With the help of the cones in our eyes we can see many beautiful colours by day, and with the help of the rods we can see shapes at night. One day we may even learn more about the invisible^④ colours around us.
