Two-Color Technicolor Photoshop Tutorial
Step 1: Open an image
To open an image, choose File > Open. Browse for the image file then click OK.

Step 2: Add a Channel Mixer adjustment layer
We will be using the Channel Mixer tool to simulate the red and green color space used in the two-color Technicolor system. With the Channel Mixer, we can simulate the color effect of two-color Technicolor by merging the blue and green channels to create a teal channel (From RGB to RG).
In the layers palette, click on the New Adjustment Layer button and choose Channel Mixer.
