1 COLORS By Ali Farrokhi

2 What Is Color? Color is the aspect of things that is caused by differing qualities of light being reflected or emitted by them. To see color, you have to have light. When light shines on an object some colors bounce off the object and others are absorbed by it. Our eyes only see the colors that are bounced off or reflected.

3 Color And Light The sun’s rays contain all the colors of the rainbow mixed together. This mixture is known as white light. While artists consider black a color, scientists do not, because black is the absence of all color.

4 How Many Colors Do We Have? psychophysicists ( people who study human responses, like seeing color, to things in the world, like light ) 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. 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.
