I have used Purpleheart in for pens and a few other misc. projects. In my experience, machining the wood is what turns the wood brown. I haven't had that problem with the finish. As DJBPenmaker said, a blowtorch will bring back the color. I find it easier to control the color change with a heat gun. If you can, heat the wood while the lathe is on WITHOUT the bushings in place. I use unused brass tubes as spacers. The bushings absorb a lot of the heat so it is hard to get a consistent color across the wood.

If your CA glue ends up being the actual cause, toss it and get a different CA glue. I haven't used every glue out there but I can confirm that 2-P10 and Bob Smith Industries are both great quality and won't change the color of Purpleheart.
