You are not wrong; it's rare that it would break a different chosen (I think its a specific scene with T3 core broken and T1 minor unbroken) but that would show up as red as well. However if it breaks their own distortion it will show red too (which I think would be more common), as seen below:Tiny correction to this part: If it´s red it means it will ruin a DIFFERENT CHOSEN´s distortion (Usually cuz it´ll cause a break that ruins it. This can be avoided by triggering the other chosen´s distortion first since that protects them from breaking in this way.)
I cheated to force 100M+ fear on day 1 (because I didn't have a save on hand to do so), and even without any other Chosens it would ruin her selected temptation distortion. I'll edit my original post for completeness.
