Was the Root Beer can yellow?

This is a tricky question! It depends on what you mean by "the Root Beer can."

* Historically: Root beer cans have come in a variety of colors. There's no single "standard" color that was *always* used. Early cans might have been more likely to be plain metal, then possibly red or brown to match the drink.

* Modern times: Most root beer cans today are brown or red, but some brands have experimented with other colors.

So, without knowing what specific brand or time period you're referring to, it's impossible to say for sure if "the Root Beer can" was yellow.

Perhaps you could clarify your question? Are you thinking of a specific root beer brand or a certain era?
