Color technique

I've seen several films that use a technique that looks like the colors are separated from each other. I'm guessing it's some kind of optical effect, but I was hoping there was a way to replicate it in AE. A couple of examples are below.

Thanks!

you can separate the rgb channels manually using an effect like channel combiner -- add the effect, then set 'red' to 'red only', duplicate the layer and set green to green only, duplicate again and set blue to blue only. then set the top two duplicate layers' blending modes to 'add' and then offset the positions of any of them to 'separate' a channel or two.

i believe that twitch from videocopilot.net can do this type of thing with one effect (and one layer).

Kevin's right.

There's also a pixel bender plugin kicking around the net somewhere that is for mimicking chromatic abberation that may also be of use.

Thank you! Knowing the name of the phenomenon was the key
