Channel

Description

Object that stores information about a color element in the image, analogous to a plate in the printing process that applies a single color. The document’s color mode determines the number of default channels. For example, an RGB document has four default channels: A composite channel: RGB; and three component channels: red, green, and blue. A channel can also be an alpha channel, which stores selections as masks; or a spot channel, which stores spot colors.
