Description farid 2017-05-13 05:11:01 UTC 
A color change happens in the rendered result whenever adding a transparent PNG over a track with track effects (could also be without but havent tested).

1- add a transparent png over a video that has a lut applied to the whole track.
2- render and you'll notice a color change in the png region.

The workaround is to add a composite transition to fix the issue.
