Photographic memory is very rare in adults. People who have photographic memory can take a picture in their mind and remember exactly what it looked like, or read a book in their mind. Other kinds of memory are motor skill and factual. Motor skills are things like walking and riding a bike. It makes it possible for you to do them without thinking.
Factual memory is used to remember telephone numbers or the story line of a book.
Color Color really isn t what most people think. Color is light reflecting off the pigment in the objects you see. If you re looking at a shirt, the light bounces off the pigment and hits your eyes and all other colors absorb in. You see just the color that is reflected. That s why you can t see in the dark.
