Anyone has a good tip or app that can change more than 200 images of color?
And it's necessary to have a clone of the image? (@2x)
Just asking. Thanks

The only two options I know of are Adobe After Effects, or Photoshop's batch actions. Alternatively you could try writing a python script that recolors the image.

And if you've skinned SD assets first then don't try making @2x versions out of them. You should've skinned @2x first, then downscaled the images using Image Scaler
