how many colors exist
There are no certain answer of how many colors are there in the world.Careful measurements of our visual systemâs best performance have been made by psychophysicists . They have shown that we can see about 1000 levels of light-dark, 100 levels of red-green, and 100 levels of yellow-blue for a single viewing condition in a laboratory. This means that the total number of colors we can see is about 1000 x 100 x 100 = 10,000,000 (10 million). A computer displays about 16.8 million colors to create fullcolor pictures, really more than necessary for most situations. However, the answer is not quite so simple.
