Puppy is a wonderful, neutral to warm light brown (no shimmer). I often wear this as a lid color when I want a "natural" look, or if I'm going to wear a very vibrant lipcolor. As all Stila shadows are, it's well-pigmented and lasts all day. Besides, I just love the name - who wouldn't want Puppy?? :)
Puppy is a warm matte medium brown. I usually use Puppy in the crease with Wheat on the lid. This looks beautiful paired with a red mouth. One of my favorites!
