I like it too! I've got dark hair, but i use the taupe because it looks more natural with my light skin. Like 008 said, it gives you a more groomed look while still looking very natural.
If you like other Smashbox cosmetics, check out the kits on qvc.com. It's a great value! There's a 9-piece kit on there right now with the brow tech & brush, primer (which i also love), cream eyeliner & brush (also a fan), eyeshadow trio, blush, lipstick, and lip gloss for only $53.25 (retail value us $106). The brow tech and brush by itself is normally $38. Just something to keep in mind
