Would you miss the color blue?

In one of the best pranks I know, you leave out a bowl of M&Ms. Unbeknownst to others, you place a smattering of Skittles directly underneath the M&Ms. Most people who eat M&Ms (at least in my friend circle) do so by the handful. So, all you have to do is wait for your victims to grab a handful of candy and shove them into their mouths, releasing a strange mix of chocolate and tangy fruit all in one go.

The confusion that appears on their faces is priceless.

It's a mostly harmless prank, but it works because you can find M&Ms and Skittles in roughly the same shades of color.

But that may not be true for much longer.

In a recent long piece by the New York Times, more and more food companies are searching for all-natural food coloring substances - including the folks at Mars Incorporated (which owns both M&Ms and Skittles). The hardest part for companies that are making the switch to all natural colors? Making the color blue. It turns out that some natural ways of making blue change the taste of our favorite candies.

But here's the thing: We didn't always have the color blue in our M&Ms. And that was OK. Do we really need blue food? I mean, my candy prank would still work without blue M&Ms.

What's your favorite M&M color? Tell me in the comments.
