They (FOJ & PP) work very well layered with other stuff or buffed out for me. I am an NC15 in Winter, but more like NC22.5 in summer LOL. I also think it depends if you gravitate towards cool tones or warm tones, so if you don't like the cool tones, good reason to swap them or exchange. I prefer to swap, since I shudder to think of make up this quality being destroyed, but you have every right to return it if it isn't for you.
I don't think Pink Tea is a must, I would get Pink Cult instead if it came to a choice between those.
I have not used my IF yet, and it looks so boring in the pan. I don't want to swatch it if I decide to swap it. But I am hoping someone can tell me it transforms into something more dramatic on the skin...
Maybe I am just spoiled by the bright colors like PP, MM + Early Morning and Fresh Honey, the MB from Naturally?
