If you've never worked at Walmart you might not know that there is a uniform color code for Walmart stores across The Lone Star State and around the country.

And since each store from Dallas, TX to Denver, CO, shares the same color-coded emergency announcement system, it's not a bad idea to brush up on what each code means.

Today, let's learn what each color is and what they mean. Who knows, this information could save the life of a stranger, someone you love, or even your own.

Going to elementary school in California, I vividly remember practicing hiding under desks and standing in doorways during earthquake drills. That's not nearly as scary as practicing being bombed, like they did during The Cold War, or active shooter drills that kids do now.

If you're ever shopping at Walmart and hear a "Code Brown" over the intercom it means that there is a shooter on the premises. If this happens you should go toward an exit, if you can. Thanks to Common Cents Mom for this information.

There are 7 different codes that signify different types of emergencies:

RED
