This settles it.
The second argument is related to neural biology as JOE digs out our old leaving cert biology textbook. Light enters your eye through the lens as different wavelengths correspond to different colours. The light hits the retina in the back of the eye where pigments fire up neural connections to the visual cortex, the part of the brain that processes those signals into an image. The first ray of light is made of whatever wavelengths are illuminating the world, reflecting off whatever you’re looking at. Your brain instantly figures out what colour light is bouncing off the object that your eye is fixed on, essentially deducing that colour from the “real” colour of the object. The good people at Wired actually undertook a study to determine the red-green-blue composition of a few pixels to determine its colour.
So that's the colour issue settled but it didn't stop Twitter from having its say.
From this day on, the world will be divided into two people. Blue & black, or white & gold. http://t.co/xJeR7GldwP pic.twitter.com/i6BwVzPzSZ — Ellen DeGeneres (@TheEllenShow) February 27, 2015
I don't understand this odd dress debate and I feel like it's a trick somehow. I'm confused and scared. PS it's OBVIOUSLY BLUE AND BLACK
