Anyone ever had a problem with purpleheart turning brown on them? Any remedies? Here's the story...

This morning I'm turning a purpleheart pen blank and as I'm turning I notice it's becoming a dull purple color. No big deal cause I'm confident the finish (CA glue) will bring the purple tones back out.

Well I begin to sand and realize the blank keeps getting brownish. By the time I'm done the blank is brown. I was using the rolls of woodturner's sandpaper from Woodcraft (brown color) to sand. Possibly cause? I'm attempting to post pictures. This normal?

It will change to purple with the ultra violet light. Just wait a few days.

You are not the first to find the colour change. A recent thread.

Just do not put this in direct sunlight as another person did for a table top. He ended up causing the top to warp.

Ok. Good to know. Thank you for the replies!

Friction apparently also caused it to turn purple. I was turning some this morning and it's really brown except for areas where I rubbed the bevel too long or hard. Those are purple. A little sanding made the whole thing brown again.
what I usually do is set my purple heart hand mirrors out in the window for a day to really pick up the purple color.

I used purple heart in a end grain cutting board. Brown also.
