I'm using a Black and White image texture for my displacement modifier. The trouble is that the displacement is extruding the white bits when I want the black parts displaced instead. I don't have an app to reverse the colors. Can the values be flipped on Blender?

4$\begingroup$ There is an "invert" node in the shader editor which does just that. Alternatively use a color ramp and flip the black and white values $\endgroup$– GorgiousCommented Feb 13, 2020 at 8:21

@Gorgious is correct, however there is an alternate means to edit your image in Blender that I wanted to share. In Blender load in the image in the UV Editing workspace (ignore any UV wrapping etc). Then go Image->Invert->Invert image colors. Then you go Image->Save As and now you have an inversed texture which you can directly load in and use as you were previously.
Result:
