Great colors to create a neutral palette.
I really like Stila's shadows. I have 4 in various shades of brown, with Mahogany being my favorite at the moment. It's a gorgeous warm, reddish brown that looks great in the crease. I've been finding the empty palette's and refills all over the net at very cheap prices. Haute Look has been featuring Stila about every 4-5 weeks and you can get the refills and palettes for $6 each.
The colors blend very nicely, but you need to use a light hand to prevent excess fallout. I hope that Stila decides to expand their colors a little more. You get a lot of product for a really great price.
