I don't believe there is anything you can add. If you want "brighter" as in shinier, you need to get a semi-gloss or gloss to begin with, which is not what most people want on their ceiling. If you want "whiter" paint, then you buy the whitest color that you can get. Most white paints for houses are slightly off white, grey or beige or even blue or pink. But you can get absolutely white if you want it. You cannot, however, take a tinted paint, and make it whiter.
