All decomposed images are grayscale images, because they are representation of the color models' different channels. Modes A layer containing a green leaf pattern was combined with the portrait layer. These images show the difference between Color and Hue mode. Channels These figures show the result of adding color to a channel. This duotone image was created using a blue and a yellow channel.
