moron question about powder shade

[Laurahead108]

Quick and dumb question: I want to get a compact powder to set/touch-up my new SFix fluid foundation (NW20). Do I get a powder in the same shade, or does it oxidize and change color? I can't get to a Mac store to try this out.

Many thanks,
laura

I would say get the same color, or a sheer translucent one like blot or pro translucent because then you don't need to worry about it.

I know that it does oxidize a bit but not too much compared to other foundations. I'd also recommend the translucent, especially if you don't need too much coverage.
