Color tint on image

Hi, I'm having trouble getting photos to look correct once uploaded. They appear tinted. Is there a setting somewhere where the theme might use a color as an overlay effect on images?
I saved the images as sRGB. They look fine in the preview thumbnail when clicking on EDIT but tinted on the page.
See screenshot attached.
Does anybody have an idea here?

Thanks - Markus

 

Ok got it. Only in the setting "Inline" in the editing mode there's no effect. All other image/text combinations apply an effect. So I assume this is an overlay to be defined in the color-themes. 

Correct.
