Does anybody have an idea on how long the paste and gel colors last??

Thanks....

I had the same question This is straight from an Americolor rep's mouth:

"These colors have a one year warranty, meaning that they should last a year on a store shelf and still be good. Truth is they often last longer, on the shelf or the consumerâs cupboard. "

Thank you, Pottedmeatchunks for your response on the food coloring.

I had colors for several years
There is nothing in them that would spoil. Never put anykind of sugar or grease into the container;
use a clean toothpick or knife etc to remove the color it will last 'forever'
