If you don't have time (or the inclination!) to do an entire makeup application, what one or two items do you use to bring color to your face? If you're short on time and can only apply a couple of things, what do you reach for?

(I don't have any answers to this question myself, since I haven't worn makeup in years. But I am considering dipping my feet back in and am wondering what the best purchases would be to start with.)
