The parts of the human eye that are responsible for color perception are called cone cells or photoreceptors. RGB is called an additive color system because the combinations of red, green, and blue light create the colors that we perceive by stimulating the different types of cone cells simultaneously.

As shown above, the combinations of red, green, and blue light will cause us to perceive different colors. The RGB color model uses parts.

These are represented as values that range from 0 to Thus if you have parts of Red combined with 0 parts of both Green and Blue, you'll end up with Red. Similar is the case with Green and Blue. There is a way you express these values, as explained in this table below. These three colors are what we call Primary Colors , that you can see within the color wheel shown in Figure 1 , below. Figure 1: Color wheel with three Primary Colors. Multiply variations of Red with a similar number of variations of Green and Blue, and you end up with 16 million colors!

We won't get into all 16 million colors for now, but let us get a little more creative and mix these 3 Primary Colors to make 3 more colors.
