Dior foundation 010 in MAC?

Possibly an NC15 or NC20, depends on what your undertone is, pink, yellow or neutral. I have not used Dior foundation but I am an NW15 in Mac as I am very fair with pink undertone and I am porcelain in Estee Lauder. If you have warm/yellow undertones you will be an NC in MAC and if you have pink/cooler undertones you will be an NW.
