There's another crazy color-changing image on the internet — here's what's going on

I first saw it in a retweet from Business Insider's Steve Kovach this afternoon, and I have to admit it's a little strange: in TweetDeck's preview, for instance, the nails and lips appear pink, but if you open the image up in its own window, they're very dark red. In addition to specifying red, green, and blue pixels for each dot of an image, some image formats can also specify a transparency value that determines how much you can see through the pixel to whatever is behind it.
