I'm looking for a name for the effect when there's a layer over another layer so that one of them always adjusts so that it has always the opposite shade of spectrum. So I want a title to look black on white backgroundand black on white background.
The top layer has the blending mode 'difference'. I don't think there's an official name, but I'd call it a 'difference effect'.
I think it could be, Inverted? Negative?
The way I would do this is taking te text as a mask and invert the curves, so the image is a negative.
Required, but never shown
