If that doesn't work:
3: Grab the slider for MAGENTA SATURATION in Lightroom and pull that down..
These two methods work 100% for 90% of the time and when they don't it's only because there's a purple object in the picture. It then becomes a little more complex in that you either have to protect that object with a local filter or be prepared to lose the purple colour of object or keep fringing.
I use the very same approach all the time when shooting birds on tree branches. Since very few birds (at least in my yard) have purple colors, it works great.
