As the dust settles on #TheDress debate and the naysayers start to see that the dress is obviously blue and black, I've realized that there is an underlying lesson to be learned from this internet sensation:
People see things differently based on their circumstances.
This is an important reminder. As professionals in the web design world, it's something we need to constantly keep in mind. Whether it's due to screen brightness, environmental lighting, time of day, or some other external factor, there's inevitably going to be a number of considerations to take into account when designing for the web.
Sifting through the hundreds of articles on #TheDress, you'll find that some postulate that it might be your emotional state that's causing you to see blue and black vs. white and gold. Could this be the real reason? I can't answer that, but what I do know is that it's yet another factor to take into consideration.
