It's similar to the trick where you stare at a B&W pattern on a page then look at the wall to see the inverse of it.
Of if you wear tinted sunglasses the world looks (insert color) at first then a while later you don't notice. When you take the glasses off things look...well brighter...but the colors are a bit odd for a few minutes there too.
Or the bunch of other optical illusions where you surround a color with others and it looks different.
It's not some great big mystery for anyone who works with photography (or anything similar that deals with lighting and color). That's why monitors are calibrated to certain colors and brightness otherwise you'd never get consistency. It's why artists draw/paint/etc. under specific lighting. It's why you put makeup on in front of lit mirror with a certain color bulb. It's why home depot sells warm, natural, and cool colored lights. etc etc etc
I can't believe people are actually making a big deal about this.
