  • What is color constancy and how does it trick our brain into seeing colors that aren't really there? WIRED's Robbie Gonzalez and neuroscientist David Eagleman use ambiguous photographs and giant props to explain light, color and the science of illusions.

        00:30 yea it's word and totally tricks me, but one of the first things I learned in painting is "a color isn't a color until it's next to a color" so there's that I guess.

                          MIND BLOWN! I normally think as the dress as blue with black, but the TIP was that!, if I just think about that it is a white dress with a blue light, my brain suddenly sees it as white!

                            What if my brain thinks the dress is blue and gold? I think I may be a freak of nature.

                                    Let's be honest, after you showed me that the shoes was pink and white, i started to see it that way, but before i would have said grey and teal. It's kinda funny how our brain and eyes are tricking us :) Nice video btw, good to know more about our body and it's secrets!

                                              Took a screenshot of the strawberries, put it in photoshop and corrected for the green cast ... strawberries are bright red. So, grey strawberries fool photoshop?...what gives?

                                                so there are small shades of faded -out red and because of that they go on every strawberry making us think theyre red..
