If you hadn't pointed it out, I wouldn't have even noticed those pictures had any effects to them. I'm guessing chromatic_aberration is that 3D coloring trick?

I guess wikipedia explains this better than I ever will, but in a nutshell, it's an effect caused by camera where colors get bit distorted. Have gotten popular in games as well. Usually it's really subtle effect (like first and second example), but if artist has no idea how to use it, then it can look like anaglyph stereogram to naked eye.

It's pretty easy to distinguish the two, if red/blue edge moves same amount of pixels on objects that should be near and far (wherever you are~~) then image doesn't have any depth and thus is badly applied chromatic aberration, like the last example image.
