Personally, I hope to never see my brain.
I totally agree with you, though.
Does anyone here ski or snowboard and have color-tinted goggles? When you first put the goggles on, the snow appears to take on the same tint as the goggles, but your eyes adjust fairly quickly and the snow looks white again after a few minutes. Then, when you take the goggles off a bunch of runs later, the snow appears to take on a tint that is the negative value of your goggles. This is because your brain applied the negative value to your vision in order to cancel out the goggle tint.
Brains!
