The Multi-colored Dress
On February 17th, 2015 an image of a dress went viral on the internet. I initially saw it on the local morning news (one of the reason that I really only watch the local news for five minutes-long enough to see the forecast). It went viral because a consensus could not be had on the colors of the dress.
As I often tell my costumers--get samples of the color(s) you want to paint and paint a few spots in the room to see how the light in the room throughout the day will influence the color. This is what is going on with the whole dress color disagreement.
Wired Magazine posted an article titled The Science of Why No One Agrees on the Color of This Dress. It is a short read and I recommend it for anyone thinking about painting.
