The video above shows how you can create 'color channels' for use with images in Clip Studio Paint. The application has no feature for color channels so a workaround is to create them via level corrections and then use layers and combine those with transformations of the layers. You can then build up all kinds of unique colorful designs. You can do this with photos but equally you could use it with text / type as well as sketches and drawings to create interesting color shifts in your images.
The first step is to use the layer menu and duplicate the main layer (the image) and create three layers. The layers are going to be the red and green and blue channels. The duplicate layer command is applied twice so you can now see three layers in the layers panel.
Select the red (and then green and then blue layer channels in turn) and go to the edit menu and tonal correction and level correction command for each.
While in level correction, for Red you have to go to the green and blue entry (for the green, go to the red and blue entry and for the blue, goto the red and green entry). In all those, goto to the bottom of the panel and go to the white marker in the output slider (far right) and move it to the far left in all those cases. Leave the red entry untouched (for the red channel), the green entry for the green channel etc the same. Now you will see a red and green and blue image in the layers panel.
Now go to the layers panel, select the red channel and go to the blending mode and set to lighten. Go to the green channel / layer and set the blending mode to lighten as well. Leave the blue as normal. Now you will see the image as the original source image.
Go to the red layer and then edit menu and transform and select one of the methods such as free transform (as above). Move the bounding box points around and transform the image. You can distort the layer in all kinds of ways. Once you are happy, click OK. Go to the green layer and then repeat the transform command but transform the layer in different ways such as rotate or scale it. Repeat (but with another different transform) for the blue channel.
You can also use the mesh transformation found via the transform menu. You can then manipulate the points of the mesh to distort the inner part of a particular layer / channel (in the above, the blue channel but equally it could be the red or green).
You can also make the image even more complex as you don't need to have just one blue channel / layer, you can also duplicate the red or green etc and then apply a different transformation to that to make ever more complex designs as well as use different blending modes. The results may become quite messy but all kinds of color shifts can be created.
Once you are happy with the result, go to the layer menu and flatten image or perhaps apply effects / filters and then flatten the image or export to other applications.
