Did I buy the right foundation is there a difference?

Ok I just bought porcelain lifting 20 C in the shade of a line great price, but I usually wear light shade (As Ivoire 10, etc.) So, how does the same porcelain 20 tint shade Porcelain 10 NC? here is the link I thank you in advance guys opinions! http://www.lancome-usa.com/makeup/foundations/renergie-lift-makeup-spf-20.htm

they look really similar. I think it should go, just be sure to mix your neck too so you will not line orange on the jaw if it is too dark
