In this short talk, the presenter explains why the viral dress image split viewers into two camps—those who saw a white‑gold dress and those who saw a black‑blue dress. He attributes the split to the photo’s ambiguous lighting, the phone camera’s exposure adjustments, and over 30 unconscious visual processes that act like a mental Photoshop before the image reaches consciousness. The speaker argues that a person’s typical lighting environment (artificial indoor light versus natural outdoor light) trains the brain to interpret ambiguous colors differently, leading to the divergent perceptions. He concludes with three lessons: (1) our brains constantly manipulate reality, so we can’t fully trust our perception; (2) we should not judge others for seeing things differently, as their visual experience is shaped by their environment; and (3) the lighting environment we spend most time in profoundly influences how we see the world.

Remember the dress that broke the Internet? Some people looked at and saw a white and gold dress. Other people looked at the exact same image and saw a black and blue dress. Well, the reason this happens is absolutely fascinating, and it's proof that your mind is constantly manipulating your reality. So let's start with the picture itself, which was taken on a cloudy day. And the phone that took it kind of highlighted some areas and lowered light in other areas, creating an ambiguous image. Now, I know it didn't feel ambiguous to you because your brain hates uncertainty. And so your brain automatically disambiguates situations that are unclear. So when you looked at that picture, you are a 100% certain that what you saw was real. But what you may not have known is that there's over 30 processes happening unconsciously before an image ever even reaches your conscious mind. It's kind of like a mental Photoshop. So why did you see the image the way that you saw it? Well, it all comes down to the environment that you spend most of your time in. If you're in artificial light most of the time, you most likely saw the dress as black and blue. If you work outside or in natural light most of the time, your brain has learned to deal with images according to that environment, and you probably saw the dress as white and gold. So there's a couple lessons to learn here. Number one, you can't always trust your brain because it's manipulating reality all the time. Number two, we can't get upset with other people because they see reality differently than we do. It really just comes down to the environment that they live in. And number three, the environment you're spending most your time in has an enormous impact on how you see reality.
