Like the description, the picture explains everything

This doesn't just happen on THIS character, all others too.

happens to everyone!

And even with matching textures, you cannot eliminate it completely.

With Photoshop you could give it a try, but as said before, You won't get rid of it completely.
When using Photoshop, you could load the body texture, create a copy of the layer and delete the original one(no worries, you will not delete the texture. I however recommend making a backup). Then go to Adjustments and choose one of many color tweaking options(I prefer Saturation/Hue) and change the levels of red and green.

I tried it myself once, but gave up since the result may even look worse. If you want to experiment, you could also make a screenshot with perfect light and load that as well into photoshop. Like this you could compare the modified body texture with the throat texture.
