Is the color of glass cola bottles green?

Here's why:

* Green glass: This is the most common color for cola bottles, especially older ones. Green glass is known for filtering out UV light, which can help preserve the flavor and color of the cola.

* Clear glass: Some cola bottles are made of clear glass, particularly for limited editions or specialty products. This allows the color of the cola to be fully visible.

* Brown glass: Brown glass is also sometimes used for cola bottles, and is known for providing even better UV protection than green glass.

So, while green is the most common color for glass cola bottles, there are variations depending on the brand, product, and era of production.
