I recommend DxO to develop raw stills, then export or "share" to LR for any final adjustments. Assuming you shot a Macbeth card as well, there are tools that will zero out any color changes.

I never shoot on Auto WB though that's not the issue. I always either custom white balance, or set on daylight. The whole image isn't pink or green, it's just the highlights. There are posts from people with the same issues from different cameras. It's something to do with Highlight Reconstruction where the program tries to re construct the detail but ends up changing the colours and there is no way to turn it off.

I don't get how I can take the same picture with the same settings on my GH3 and pull the exposure right down and have no colour change but have this camera even with a subtle change turn bright pink

ABove is the RAW file if you want to try it out yourself. This is it with the exposure brought down to really show off the extent of the pink.

I have tried it in Lightroom 5.6, Photoshop CC with camera raw 8.6 and Raw Therapee and all of them do the same thing.

If I do an exposure adjustment and lower highlights using the in camera raw editor there are no highlights that turn pink they stay white all the way.
