In addition to white angel's trumpet plants, Brugmansia does come in other colors, including yellow. The angel's trumpet shown in this picture is tinged with a light salmon pink at the ends of its flowers; in a certain light (as here), it can be almost a rust color. These sub-tropical and tropical flowers are treated as annuals in the North. If you're looking for a trumpet-shaped pink flower that is more cold-hardy, one possibility is Stargazer lily.
Don't confuse angel's trumpet with Datura stramonium. The latter is commonly referred to either as "devil's trumpet" or "angel's trumpet"; for purposes of clarity, I prefer to call it "devil's trumpet," to distinguish it from Brugmansia (angel's trumpet).
Angel's trumpet plants can grow several feet in height; this fact, taken in conjunction with their showy flower displays, means that they can make a "big splash" in the landscape. Many who treat angel's trumpet plants as annuals grow them in pots and use them as focal points when in bloom. But used in planting beds, their height would make them a valuable addition to the back-row.
