CMYK or RGB.
CMYK—Cyan, magenta, yellow, and black are the colors of ink used in four- color process
printing. These four colors are combined and overlapped in a pattern of dots to create a
multitude of other colors.
RGB—Red, green, and blue light are added together in various ways to create an array of
colors. Select this mode if you are using images for on-screen presentations, the Internet, or
mobile apps.When you create a new document by choosing File > New, each new document preset, like Print
or Web, has a specific color mode. For instance, the Print profile uses the CMYK color mode.
You can easily change the color mode by choosing a different option from the Color Mode
menu.
