Does anyone know of a hard pastel pencil?

I usually use Generals, but I have a hard time finding a lot of the colors, unless I buy a whole set just for one color. You can see some of my artwork at www.MorenzArt.com I go through a lot of browns, especially if I am drawing a black person. I can get a set of four pencils with light flesh, beige, sanguine, and burnt sienna. Thanks
