I bought blue-red glasses a couple of years ago (not the cardboard type) to use with things on the net that were in 3-D. This morning after watching Astronomy Picture of the day(by the way what happened to our link from CC?), I noticed that after taking the glasses off and covering one eye --right eye / blue lens that the picture was bluer and then covering left eye/ red lens the picture was more yellow. At first I thought old man cataracts, etc. but in just a minute this color change disappeared. I'm sure there is an explanation that involves cones and transient imaging or something, but I thought it was interesting. Try it!
