Different Colors in Editor and Play Mode

I made a underwater pp effect with a blendable but the Colors in Editor and Play mode are different.
Whats blueish in Editor is black in Play mode. What can I do ?

Please help, I don’t know what to do about this.

Check, if your post process settings on your game camera. I bet that something like camera’s post processing settings are overriding post processing volume, or other way around.

Thanks for trying to help.

Well, Problem is solved now, I was deriving the zenith Color from the sky sphere bp with a Collection Parameter.
However the Parameter didn’t got updated and I had to move this section out of the Standard construction script into the Event graph.
