CoverGirlOutlast All-Day Stay Fabulous 3-in-1 Foundation Soft Sable, 1 oz (packaging may vary)

Is this product water proof?

Is this a good foundation for stage?

what color would work for a fair/medium skin tone with rosasia?

I found similar questions, but no answers for which colors are for pink undertones. I'm light/medium skin tone with pink undertones. Can someone help?
