Difference blend mode question

[spb155]

Hello!

First time poster here. I just started doing Adobe InDesign tutorials the other day. 

I'm working on this one: https://helpx.adobe.com/indesign/how-to/ebook-cover-design.html?playlist=/services/playlist.helpx/pr...

I want to create the same blend as seen here in the word "Emerge". I see they selected the "Difference" blend option with 100% opacity, but I tried it and it didn't do what their tutorial shows. I tried messing with the opacity and nothing worked. 

I can't figure out how to make the word look "inverted" or like an X-ray, with the white and black colors inverted.  

Attached is a screenshot of what it looks like in the tutorial and how I want it to look. 

Any help would be appreciated. 

Thanks!

I think I got it figured out. 

I went to Edit - Transparency Blend Space - Document CMYK and I got the desired effect I wanted. Just needed to experiment with it a little bit. 

Thanks!
