Blue ambient occlusion that won't go away and not sure where it came from.

[ATTACH]510112

There is some strange blue darkness that is covering my entire scene. It seems like the colors of my lights and HDRIs are inverted. I’m really not sure. Also the previews of my lights and textures in the properties panel show the blue darkness. I don’t have any ambient occlusion on the scene and when I turn off all lights the scene is completely dark. Has anybody else had this problem? Please help.

That black/blue look is the result of the black level adjustment you added to the scene’s color management…
Uncheck the entire “Use Curves” section or reset the black level to more conservative settings and the scene should look as expected.

Thank you very much!
