How to make color adjustments by mixing color channels
Posted On March 19, 2021
Our eyes are unable to pick out many different levels of light and darkness. But they are much better at distinguishing different colors. In order to get the full photographic color on screen, we make use of the RGB model, which is a system to stand for colors. R is for red, to store the amount of red. G is for green, to store the amount of green. B is for blue, to store the amount of blue. The individual sets of values for the color data are so-called channels. Sometimes, one color channel might have high values and the other color channels have low values. To fix this problem, we can share some of those high color values around. Take values from one channel and add them to another. This is channel mixing, which photographers usually use to correct the exaggerating color. Though lots of photo editors with channel mixer adjustment are available on the market. Many of them are very difficult to use and not suitable for photo editing beginners. If you are searching for a simple tool to handle the task, please continue the reading. In this article, I will introduce a beginner-friendly software tool that helps you make color adjustments by mixing color channels.

How to use the channel mixer of Photo Effects to make color adjustments
- Drop your photo into the region "Drag and Drop Your Photo here". Or click on "File"->"Add Photo" to add your photo. You can also add the photo by clicking on the "Add" button. If you import the wrong photo into the program, click on the "Remove" button next to the "Add button" to remove the photo.
- Go to the right side panel and scroll down to the "CHANNEL MIXER" section. Click on the "CHANNEL MIXER" button to activate the function of adjusting parameters. The parameters in this section are red 1, red 2, red 3, green 1, green 2, green 3, blue 1, blue 2, and blue 3.
Red 1, 2, 3, green 1, 2, 3, and blue 1, 2, 3 are respectively the values of red channel, green channel, and blue channel. Increasing values will increase the total values of the corresponding color channel. Decreasing values will reduce the total values of the corresponding color channel and add the tones of the opposite color to the photo.
For example, if you raise the value of red 2 to 50, you will add the values from another channel to the red channel, the photo will look a little more magenta.
Then, raise the value of green 1 from 0 to 50 and it will increase the total amount of green. The photo will look a little yellowish.
The opposite color of red is blue on the RGB color space. If you lower the value of red 2 to -50, you will add blue to the photo.
If you set the values of green and blue channels to zero, you will see only the red channel representation of your photo.
- Drag the slider to adjust the parameters to fit your needs. Click on the "View" button to compare the differences between the original photo and the changed photo. To readjust the effect, click on the "Redo" button to discard the adjustments.
