L'Oreal Infallible Vanilla Foundation or Natural Rose?

[sarah.ox]

Hi guys! So I'm going to be using fake tan and the one I uses gives a nice golden colour. (Vita Liberata Rich Silken Chocolate) I don't know whether to get L'Oreal Infallible in vanilla or Natural Rose. I'm really pale so I want the foundation to match my tan but don't want to turn orange or for the foundation to oxidize so which shade should I get? Vanilla or Natural Rose? whenever I get beige or sand I tend to turn orange like an oompa loompa so what shade should I get?
Thanks xxx
