RGB Color Model, 1

Before exploring the RGB construction process, it's helpful to know a little about the RGB color model.

Various models are used to describe colors, with the RGB color model being the one used to produce the colors that we see in electronic devices such as televisions and computer monitors.

The RGB model has three primary colors: red, green, and blue. By combining them in various ways, we get a broad array of colors, from the secondary colors of yellow, magenta, and cyan, to the grays, black, and white. Understanding how these colors are made is important for producing and interpreting RGB products, so we'll take a few minutes to explore the process.
