I'm NW45 in most MAC foundations and I wear Walnut (8) in the Oil-Free Even Finish Liquid that has now been replaced by Natural Finish Long Lasting Foundation. I haven't been matched in the new formula yet, I assume it's the same. I love the Oil-Free, like LOVE it. Its my go-to liquid. I also like my NARS Oil-Free (which has also been replaced by Sheer Matte), but I think I like the Bobbi more. I only hope the new foundation is as good as the Oil-Free. Anyway. I am also Warm Walnut (7.5) in the Oil-Free Even Finish Compact, which I did not like. I prefer Studio Tech, although the Bobbi product is more like the MAC Mineralize Foundation SPF in texture and finnish, but the Bobbi is heavier in feel and coverage. Maybe cream products tend to run darker in general, because I am NC50 in Studio Tech and the Mineralize Foundation SPF. HTH.
