Hands down, the best foundation I've ever tried, and I've tried a lot of them. This is the one that caused me to lose any interest in trying another. It's oil free -- no breakouts! It has a nice texture, which just seems to melt into my skin. It goes on dewy (with a little light diffusing aspect to it), and it doesn't get oily later on. (I follow with T LeClerc powder, but I'm considering trying their loose powder when I run out.)
I have to order it online through the Piaffe site. I knew I'd be the lightest color (never any doubt there), but they've sent me samples of the darker colors when I needed something to match my skin after using self tanner. I suspect they'd do the same if you are in doubt about a color match (or you might reference your match in another line so as to give than an idea of what to recommend).
