I am wondering if your Olympus camera has the same problem when you shoot black objects in low light or indoor?
Notice that the black is no long black but towards blue/grey.
My Panasonic G3 (in the past) and Nikon D5100 have not shown such problem.
This happens whenever I shoot in low light, and I assume it has nothing to with my white balance set to auto.
Is there any setting I could adjust to avoid such colours?
I am also not comfortable with the skin tone colour, even though set to Natural and deselected 'keep warm colour'. Skin always look reddish. It is even worse when used with a flash.
