What colors do George Foreman indoor grills come in?

As of 2015, the George Foreman Cooking website lists classic indoor George Foreman Grills in four colors: black, silver, red and white. Amazon lists several additional grill colors, including teal and indigo, but these colors are found solely on older discontinued models.

The George Foreman Grill is an electric indoor grill designed to cook both sides of a piece of food at once. Food is placed on one of the griddles inside the grill, and then the lid, which is outfitted with a second griddle, is closed on top of it. The grill is also designed to drain grease and fat off of foods during the cooking process.
