Optical illusions might be a good example of this. Ex. http://www.buzzfeed.com/catesish/help-am-i-going-insane-its-definitely-blue#.hfZoPkgjK

People are freaking out over what color the dress "really is". They're projecting the property of "true color" onto the real world, when in reality "true color" is only in their mind.

The way I think about it:

dress.trueColor = undefined;
dress.reflectedWavelength = someNumber;
dress.interpretedColor = function(reflectedWavelength, observer, context, lighting...) {}

People are freaking out over what color the dress "really is".

Are they, actually? Or are they freaking out over what other people say it is?

If I saw only the text of the supposed controversy I would instantly diagnose it as a hoax for clickbait. There are colour constancy illusions, but I will not believe that this is one of them until I see two people actually taking opposite sides. However, that is socially impossible to achieve, because there will always be enough people to perversely take the opposite side for the lulz. The wording of the original Tumblr post, and the buzzfeed and Wired articles, deliberately encourage this.

What colours do you see in the dress in this picture? Not in any other picture, or the real dress, but this, the original picture that started it all. Feel free to experiment with different monitors and ambient lighting (but not editing the picture) and to give details in comments.

Here and here are two fragments of the picture I linked, expanded but otherwise unaltered, and saved in an uncompressed format. Compression artefacts from the original are clearly visible, but please ignore these and attend only to the overall colours.

Again, this question asks only about your experience of the colours, not any guesses you might make about what you would see if you were there, nor what colours you can convince yourself you might be able to see.

If I didn't know where these came from and I was doing an XKCD color survey-like thing, I'd call the colors in the first bronze and mauve and those in the latter black and indigo. (I'm not a native English speaker.) I'd call the difference between the two blacks "striking" but not the difference between the two blues, so I picked "Just show me the results".

I wouldn't go as far as to call it a striking difference, but I perceive the first image's colours as lighter and more washed out than the second's.
