What colour IS it?? The dress that broke the internet

The image was uploaded to Tumblr with the caption: "guys please help me - is this dress white and gold, or blue and black? Me and my friends can’t agree and we are freaking the f**k out"

It's the seemingly simple dress that's causing a huge stir in offices around the country, and appears to have broken the internet.

Possibly the most divisive question of the day is "What colour is it?"

Celebs have weighed in and scientists have also had their say.

The 'Great Dress Debate of 2015' has also inspired violent reactions from firm "Black and Blue" supporters.

It left some scratching their heads.

And others feeling victorious after apparently solving the mystery.
