Pixels
The word pixel stands for Picture Element. A pixel is a small part of a picture. Pixels are the little dots that make up computer screens. When you see a low-resolution picture that is grainy, the grains you’re seeing are the pixels.
Color Models
There are many different representations of Color. These representations are called color models.
Subtractive Color Models
Some color models are subtractive. These models are useful for printing. They are subtractive because they model the subtraction of light as each color absorbs light (before what remains to bounce off into your eyes). The most common of these models is CMYK which represents Cyan, Magenta, Yellow, blacK. If you have ever changed the ink in a color printer, you have encountered CMYK cartridges. Truth be told, you don’t need the black. Essentially all of the visible spectrum of light would be absorbed printing layers of cyan, magenta, and yellow. A lot of black tends to be printed, so it is more cost effective to add to add black into the model.
Additive Color Models
Some color models are additive. These models are useful for display devices. They are additive because they model the addition of light which is thrown at your eyes.
RGB
The most common of these models is RGB which repesents Red, Green, Blue. If you have ever plugged an old device into a TV with a component video cable, that is what the separate cables are carrying: analog signal for red, green, and blue.
