This thread convinced me to go out and get some HIP! I bought Tenacious (super-shimmery tan) loose pigment and Intrepid (luxe MAC Blue Brown knockoff) loose pigment. Intrepid is super pretty and amazingly vivid on my eyes, it really makes my nearly black eyes stand out. Can be used wet or dry to deliver gorgeous color, and the texture is very fine.
Tenacious is a little more difficult to blend, it doesn't seem as smooth as Intrepid, but it is much more shimmery/metallic and looks gooooorgeous on my NC45 skin, so I'm willing to work with it a little. Wheeee. None of the other HIP colors appealed to me, I think my Walgreen's doesn't have the full range of colors maybe? Either way it was a good deal at BOGO, so $6 each. I also used my fingers to apply them, I'm sure using a brush would make it easier.
