Among the MAC pencils, I love and use often Cherry, Beet, and Plum.
I also own Half Red, and it's beautiful, but for some strange reason I don't find myself using it very often.
I also have Cranapple Cremestick, and it's wonderful, but I find myself more often reaching for Beet pencil.
I LOOOVE Red Enriched Cremestick; there's no way I could have made it through last fall's deep red lip craze without it!
The only other brand I own is Urban Decay's 24/7 pencil in Envious, a luscious deep berry. The 24/7 pencils don't feel like the conventional pencils; they're gel-based, and you can really tell. They stay on well, though. I love Envious, and would happily buy more shades if Urban Decay offered others that would work for me.
