Ocellaris clown white stripe turning purple

I have 2 Ocellaris clowns in my 75 gal. tank. I came home from work today and noticed the white stripe around one of their faces has purple blotches. I also noticed it is finally introducing itself to an anenome I added 2 weeks ago. Would this be from the anenome, disease or another fish? Any thoughts or facts on this. thanks for your help!!!

 

I know that when a clown is starting to host a nem for the first time it can develop spots on its body, haven't heard of purple ones though. When they are done with getting used to the nem, the spots go away. Not all clowns will get the spots and the degree of how many they get varies. That's the only thought I have.
