I've gotten tired of hunting and roll with MAC Blot Pressed Powder in Deep Dark for now. Everything else I've worn just tends to look like too much/cakey on me. I use a simple cheapy sponge to pat the powder on my super oily forehead, nose, and semi-dry cheeks. Works like a champ to keep me from getting all oily. It claims to have no color, but it does a decent job at keeping my little freckles from showing up too bad. Looks natural, so it works for me.
I use MAC Studio Sculpt Foundation in NW45 when I want a more glammed up look.
