NC45 here with strong yellow understones! I switched from using NW40 as a concealer to NW35 I found that NW40 was too red when I just wanted to put on the concealer alone. Favorite MAC concealers: Studiosculpt, Prolongwear, Select Cover.
Concealer I use for dark circles Studiosculpt in NW35, I use prolongwear in NW35/Select Cover NC45/MUFE full cover 14 for blemishes, for brow highlight Studiofinish in NC42.
Foundations:
Pronlongwear NC45, perfect match
Satinfinish NC45, perfect match
Studiosculpt NC45, one shade too light, right undertone
Matchmaster 7.0, neutral undertone on me
MUFE HD 173, almost perfect, sometimes I notice the red in it but for the most part I think the undertone is neutral
MUFE HD 170, tad too light, right undertone
MUFE MAT 70+ is too light, 75+ is too dark
Cargo HD Powder 40, perfect match, perfect yellow undertones in powder my favorite one!
Cargo Tinted Moist. Tan, too red
Revlon Photoready Caramel, neutral undertone
MSF Natural in Dark
NARS Sheerglow in Cadiz, perfect match/perfect undertone goes on light but settles in five minutes
NARS Tinted Moist. in Cuba, perfect match and very yellow undertones
