I am normally a NW45 and I tried the NW43 in the new foundation. It was too light. I ended with NC50 I do believe. The NW45 was too dark but NC50, which still has some red in it, seemed to work. If the color is not working for you, take it back, even if you don't have the receipt. They should, at the very least, allow you to exchange for a better color.
