Optical Illusions and our Perception of Color

A fun and mind-boggling TED Talk,  that will interest anyone who thinks they can see color- especially artists and synesthetes!

“Color enables us to see the similarities and differences between surfaces, according to the full spectrum of light that they reflect. But what you’ve just done is, in many respects, mathematically impossible. Why? Because, as Berkeley tells us, we have no direct access to our physical world, other than through our senses. And the light that falls onto our eyes is determined by multiple things in the world — not only the color of objects, but also the color of their illumination, and the color of the space between us and those objects. You vary any one of those parameters, and you’ll change the color of the light that falls onto your eye.

This is a huge problem because it means that the same image could have an infinite number of possible real-world sources.”

“Color tells us… that the brain didn’t actually evolve to see the world the way it is. We can’t. Instead, the brain evolved to see the world the way it was useful to see in the past. And how we see is by continually redefining normality.”

Perception & Context: Alwar Balasubramaniam

“And what I’d like to tell you, our senses are so limited — we cannot hear everything, we cannot see everything. We don’t feel, “I am touching the air,” but if the breeze is a little more faster, then I can feel it. So all of our construction of reality is through these limited senses. So my recourse was like, is there any way to use all this as just a symbol or a sign? And to really get to the point, we should move beyond, you know, go to the other side of the wall, like in logic, like are invisible. Because when we see someone walks, we see the footprint. But if we’re just cutting that footprint from the whole thing and trying to analyze it, you will miss the point because the actual journey happens between those footprints, and the footprints are nothing but passing time.” [quote from video]



“If you just ask an opinion of how, everyone can interpret it. Like, let’s say, if a schoolteacher says, she’ll simply say, “To get to the other side.” Why the cow was crossing the road, you know. The answer can be so different if Potter said it. He would say, “For the greater good.” Martin Luther King would say, “I imagine a world where all cows will be free to cross the road, without having their motives called into question.” (Laughter) Imagine Moses comes now, and he sees the same cow walking around the street. He would definitely say, “God came down from heaven, and he said unto the cow, ‘Thou shalt cross the road.’ And cow crossed the road, and there was much rejoicing as a holy cow.” (Laughter) Freud would say, “The fact that you’re at all concerned reveals your underlying sexual insecurity.” (Laughter) If we ask Einstein, he would say, “Whether the cow crossed the road, or the road moved underneath the cow, depends on your frame of reference.” (Laughter) Or Buddha — if he saw the same cow, he would say, “Asking this question denies your own nature [as a] cow.”” [quote from video]
