The style that I'm in right now is to have pretty life-accurate colors or even a little more contrasty. What I do is shoot in the Marvels Cinestyle (which people say doesn't really help, and I could agree, I just like the dry, flat look before delving into coloring). I only correct/grade in Premiere along with my timeline. Usually what I'll do is use Color Corrector Three Way and sometimes Fast Color Corrector to adjust white balances so all of the clips are within reason, then I use the Luma Curve to brighten the whites and crush the blacks a little. If a clip is less exposed than another, I'll use brightness and contrast to even everything out.
