Example: An image with a mixture of red-green-blue (as most images are) 
Remove one element - in this case a primary - blue and the remaining red and green combine and you also get semi-transparency.



You need some other method
You need to give more information. 
What are these 'placeholder colours'? 
You mentioned a texture palette, what is that ? 
Best if you upload a couple of typical  images, maybe zipped into a file on dropbox or similar.

You can see an example of the textures here:

As each model or surface references an image, not all sectors in the image are used. Anything not used, will feature a void of color. Some of these colors directly interfere with up-scaling tools, as they border the texture. The affected outcome, is a green tint.

Removing any variants of red from these placeholder voids, resolves the issues during the process.
