Does food coloring go bad

Does food coloring go bad? I've had some natural food coloring sitting in storage for ages. I am planning to use it.There is no expiration date on the packaging so how long can I store it. If I were to buy fresh food coloring which brand would you recommend.


Food Coloring Does Not Go Bad

Food coloring does not go bad. I have had a supply of this and use it on and off year after year and it doesn't go bad.
