input: Gummy bear

In the United States, Haribo gummy bears are sold in five flavors: raspberry (red); orange (orange); strawberry (green); pineapple (colorless); and lemon (yellow). Trolli's bears are similarly most often sold in five flavors in the United States, and in the same colors; however, Trolli's red bear is strawberry-flavored, while the green is lime and the colorless is grape. Many companies emulate either Haribo or Trolli flavor-color combinations. Health-oriented brands, which often use all-natural flavors, sometimes opt for more and different flavors. For example, the boxed bulk gummis sold by Sunflower/Newflower Markets include grape, pineapple-coconut, and peach, among others.

In mathematics and physics, the centroid or geometric center of a plane figure is the arithmetic mean (''average'') position of all the points in the shape. The definition extends to any object in n-dimensional space: its centroid is the mean position of all the points in all of the coordinate directions. Informally, it is the point at which a cutout of the shape could be perfectly balanced on the tip of a pin.

- no
