The understanding of PS Channel Mixer

First we use the red-green-blue three-color graph to study

Open the channel, you can see in the 3 channels, because three colors are 255, so in their respective channels are shown as white, CMYK with the contrary, digress ~

Below open channel Mixer, perhaps many people will be surprised, what is the output channel is what, the original channel is what? The output channel is the channel you want to modify, and the source channel can be understood as the component of the other two channels that you add to the channel you want to modify (the output channel). May not understand now, it doesn't matter, the following will understand. Maybe you still wonder why the red in the source channel is 100%, this problem is related to the RGB principle composition, I will not digress.
