If your tanned your likely to be a mixture. Im more of a yellow tone but once I put on a Nc I can look too yellow. There are some shades of Nc such as Nc37,Nc41 and Nc43.5 Which is a mixutre of Nw and Nc and looks absolutely fantastic!





Also with concealer sometimes it can go a bit more in depth. Even if you are a Nc but you're trying to conceal undereye bags you will need an Nw because this will neuteralise the blueness etc.





Also depending on what concealer - Moisture Blend, Select Cover up,Studio stick etc.





To be honest best thing to do is pop to one of the counters the artists can match you up without having to take your make-up off. Promise :)How do you know what NC or NW you are at MAC with out taking off your makeup ? HELP PLEASE?
Test it on your neck (I assume you don't wear makeup on your neck...). Or just buy the one you think would work and get the other one if it doesn't work out (they're inexpensive, so it's not like you'd be losing a good amount of money).
Test the concealer on the back of your hand to determine wither your an NC or an NW
