I get mine at Nordstrom. The YSL cosmetic stand isn't at all of their stores, so you should call first. Here's the link for it on their website, but you should go try on the colors at the store.

If you read the descrip you'll see that diff colors are for different uses... color sheen, color balance, color boost, etc. The one that I use as a light foundation is #4. it'll work well with your light complexion
