IMF Rendering from Resolve
It is very important to properly manage the color workflow of your project. In the Color Management Tab of the Project Settings inside of Resolve, ensure that the Output Color Space has been set to the correct Output Color Space.

In Resolve, the IMF rendering can go wrong if the Color Science is set to DaVinci YRGB. To solve this problem, change the Color Science to RCM or ACES.
Another workaround is render TIFF+XML instead of IMF. Then package IMF using other tools like Clipster, Transkoder, etc.
