I've tried it! I doubt I'm the palest here but I usually am in a room... I haven't found my perfect foundation yet but as a colour example I was recently recommended foundation in Diorskin 100 (Ivory), which was a rather good match! (For swedes - MUS's Milk foundation is a very good match!)

I got foundation and concealer from Nicola's line via Asos.com. My foundation colour was porcelain (which is yellow-ish beige). I've seen people complain about the texture of the foundation but I thought it was ok! It's like a sort of... mousse, only not as liquid, if that makes any sense. It goes on good, I didn't need to use very much. It's a bit thin. The texture was matte for me, none of that damp feeling some foundations leave. It lasted the average length of foundations (I have combination skin), but I needed powder as a touch-up. And the colour wasn't right. I need it more pink I think, should've gone for the other one!

I've only tried it once though, since I bought it recently, so maybe you shouldn't quote me! And the packages are small, so remember that if you buy any!
