Why is bubble gum pink in color

Despite bubble gum is available in many different colors and flavors. The common flavor is known as "bubblegum" which is traditionally pink colored.

But why is it pink?

Bubble gum (originally created by Vincent Geoffrion Hughes - but it was unsuccessful and the gum is sticky and broke easily and it was abandoned) was invented by a man named Walter E. Diemer, when he successfully invented the bubble gum known as today (which is less sticky and stretch easily) the only food coloring in the factory is pink, which is why most gum today is pink.

Also, the reason bubble gum is traditionally pink is that it was the original color used by Frank H. Fleer ( the inventor of the bubble gum today, later the recipe of the bubble gum was refined by Walter; and Walter uses the color pink from his bubble gum factory!)
