There are a few ways to get the red look. You could put a red solid at the top of your composition and change its blending mode to hue (or color if you like that look more), you could use a CC Toner effect and change the midtones to a red color, you could use a Shift Channels effect to turn off the Green and Blue color channels leaving you with only red (this would mean your whites would look like pure red, which I don’t think is the look in Terminator).
After that you could do a few things to make it look more ‘robotic.’ Off the top of my head you could try a stylize>posterize effect to limit the color pallete, a stylize>mosaic effect to give it a digital look, and then maybe an animation preset like Bad TV 2 (search TV in animation presets).
If you don’t like the way that preset looks you can tweak it to be more subtle, I like to use a slider control on a null object and some expressions to control the intensity of it.
