Need to create and adjustment layer to compensate for the unwanted hue caused by lens

I'm looking for help to set up an adjustment layer to compensate for a specific lens coloring problem. Basically, I use a GoPro (on a drone) but I got a flat lens of spare parts. The sharpness is good, but the lens has a well-known problem: it translates into a pink coloring around the edges/corners. Most of the time it is barely perceptible, sometimes he jumps. It also depends on the screen, that I use for example. My TV seems to bring out a lot more than my laptop.

Here's an example - look at around 0:35 0:40 http://vimeo.com/117790732

And to try to get an idea where the question is on the frame, I took a picture of the example of the grass Frost, very early in the morning. I then crank up the saturation to 100% and this is what it looks like:

I would like to be able to compensate for this. This should probably do with an adjustment in Photoshop layer that I can then import in Premier Pro. Can anyone advise as to how to do?

Any help will be appreciated.

Thank you

Since any change in RGB channels influence the tonal scale, perhaps to the laboratory, with m/g-b/y juxtaposition and distinct tone level would be a logical choice. Here, a few sweeping curves (and a rough mask, sorry about that) need to be addressed.

The adjustment layer that results can be changed in the opacity according to the saturation of the chromatic aberration.

EDIT: Posted quickly. End of shadow of channel tweak L. red dot needs a white dot in the mask to eliminate].
