How do I extract only the stroke border of the circle so that I can apply blending options to that portion? It's the red part of that image obviously. I know of a few ways to do it such as rasterizing the layer and using a tool to select the red border and extracting that, or even just using a circular brush to erase the center, but those aren't very efficient methods and it's not going to leave me with a perfectly clean edge. I could use the pen tool also but again that's not very efficient, I'm just wondering if there's an easier way which I don't know of.
Thanks in advance for any help you can provide
