An innocent pair of flip flops is rapidly destroying families and friendships.

A little more than a year after "The Dress" debate rocked the internet, these Havaianas have started circulating on Twitter.

"What color do you see?" Twitter user @positivedemi asked.

Obviously, chaos ensued.

Some say the shoes are black and blue.

(Means "black and blue," in Portuguese)

Others, who are wrong, argue the flip flops are white and gold.

One thing's for sure: lighting changes everything.

But still, if you want to piss off your friends and family, go ahead and show them this pic...

...of obviously blue and (darker blue) flip flops.

What colors do you see? Let us know in the comments.
