#dressgate and Absolute Pitch

Postby Juuso » Sat Feb 28, 2015 11:47 am

Has anyone else started to ponder the similarities of Absolute Pitch and the #dressgate phenomenon that has been rampant on social media this week?

If you don't know what I'm talking about, it might be a good idea to google it first.

At least two things come to mind instantly:

1) This seems to be a nice example of categorical perception – people seem to really see this as either or (not as something that is in between). Some people see it as blue and black, others as white and gold. Even people who tend to switch between the two, always see it as having one set of colors or suddenly flip to the other. There is no gradual shift, it's really either or. I suppose it is quite similar to how absolute pitchers classify tones.

2) What is happening on the visual field is this... The color of light that reaches the eye, is determined by two factors. The color or the object (what frequencies of light the surface reflects) and the color of the light that hit the object in the first place. The brain is used to deducting the color of the object regardless of the changes in color of the light. Hence whether we see a white surface in blueish light (as in daylight) or in orangeish (as in incandescent indoor lighting), we still see it as white. And that is because our brains are able to see that ok, the lighting has this color, and automatically compensates for this. Therefore we still see white as white, even though the color of light really reflecting from the surface might be quite blueish or yellow.

So how does the second one relate to Absolute Pitch? Well, it probably doesn't. But it does start an interesting speculation. What if timbre could be thought of as the equivalent to the color of the light in the analogy? Chroma would then be the equivalent of the color of the object itself. Absolute Pitch recognition would then require being able to make a distinction between the two.

And where does this lead us? Absolutely nowhere, I suppose, because even I don't really believe this theory. :) LOL

If nothing else, it's a nice speculation though.

Here are a couple more links that explain the science better than I just did:
