Chanel Rouge Hydrabase in Red Ruffles is my red (a true red, not really a blue-red; I do better in brick shades so this is the best "real" red I've found). Looks great during the day also. Be sure to use a nude or red lip pencil underneath first, and fill in your entire lip surface with the pencil instead of just lining the edge.
It can take some time to find the right shade, so don't be afraid to spend a while in the store trying different demos and checking them in natural light. It's worth the extra effort to find one that really works.
