My experience is that pink is hard to cover, especially with a light color. You'll want a good quality paint -- one of the higher lines at Sherwin-Williams or Porter, for instance. Even then it *might* take a third coat.
Obviously, the best way to match the hall paint is take a sample of it to the paint store -- the old can or something with the paint on it. (Actually the best way is to have the formula from the old can.)
Next is to go through the color chips [sometimes a paint store will let you borrow one of their color decks), and even then it'll probably involve buying test quarts to make sure you're getting what you want. I'd start with a color that's close but on the light side -- the paint store can adjust the test quart to zero in on the color, and it's easier to darken a color than to lighten it. Often paint stores will give a bit of a discount on test quarts, so you should ask about that.
If you're intent on matching the color be ready to put your patience to the test. Sometimes it can prove to be nearly impossible. Just a thought -- you may, at some time during the process, want to consider a color that's close to the hall paint. Close can look as good as exact.
oh... and I don't see a need for primer.
