What Bare Minerals shade would be closest to Lancome Ivoire 4 N?

Looking to change from Lancome liquid foundation to Bare Minerals to help with my acne problems, does anyone know a close shade match? I have fair skin with a slight tan and yellow undertones...|||I would say go to your nearest Ulta, Sephora, or Bare Minerals store and ask to be color matched.|||I absolutely LOVE ORIGINAL SPF 15 Foundation i've been struggling for a long time to find a foundation that actually works with my skin, and this is the only one that does. It covers up redness in an instant and leaves skin soft and smooth. I always have dry skin and could never use powder foundation because it seemed to dry out my skin even more, but BareMinerals is perfect!
