There may be times when you want to play around with some elements in your images. Perhaps you want to change a color to a more suitable one in post-processing. One of the tools you can use in Photoshop is the Channel Mixer. It is a simple process that allows you to change the color of any element in your image to any other color under the rainbow. The Channel Mixer adjustment is widely used for making good black and white image conversions, correcting color casts, and exaggerating color. But why not use it for fun too, such as changing the color completely!
