Thank you! The only way people will actually see the true color is if you extract it; just viewing the image as a whole will only allow us to perceive it in an illusionary form. I did the same exact thing and the colors came out white and gold, similar to yours. There's also another reason why white and gold are the true colors other than this method (and the so-called "creator" of the image claiming it is); white and gold are transitionary colors in this situation. White and gold can both darken into blue and black, but a black cannot brighten into gold and blue cannot brighten into white. Additionally, the dress shown on a website that is depicted as black and blue is not the same dress as in the photo; it has no sleeves and its frills are different. Problem solved!
But anyways...I think the most important thing is, we're all never going to agree and it...and it's just a dress. If this is more important than what matters are going on in our countries today, that is just silly.
