I was hoping one of the face powders would be light enough for me to use (well, other than as a bronzer!) but I am sort of glad it wouldn't work because I would be compelled to purchase it with the gorgeous packaging and it would be expensive. I love the look of the whole collection.
The lighter one is NC/NW15 and has a translucent quality. Unless you are much lighter than NC/NW15, you should be fine. I love the Sheer Mystery as a setting powder as it does not cake up at all.
