RGB mode

As I mentioned earlier in this chapter, RGB stands for Red, Green, and Blue, which are the three color channels in your image (Figure 3.1). Not coincidentally, these are also the three color phosphors used in your computer monitor to display color. The combination of these three channels, viewed simultaneously, brings the full color in your image to life. It’s important to understand this concept, as many of your color selection and correction options allow you to adjust these colors independently. (See the color plate section of this book for a full-color example of RGB mode.)

Figure 3.1. An RGB image is made up of three separate color channels: Red, Green, and Blue.
