These are the M&M's we know and love:
But did you know that in the 1980s, M&M's had a different look?
They were brown...
...yellow...
...green...
...orange...
and tan (?!).
BUT THAT'S IT. Which means that M&M's looked something like THIS* in the 1980s:
Thankfully, someone realized that spiraling into a Thanksgiving-hued vortex of despair isn't what you want when you tear open a bag of M&M's.
So they nixed the tans, reintroduced the reds, and added blue.
And everything was right with the world.
Never change, M&M's!
