Blue-Red glasses
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!

Its kind of like this American flag illusion. Check out some of the others on this page, a couple of them are really cool. So do you always start your day with the 3-D glasses or was this just a special event for the astronomy pic of the day?
Not every day just special things in 3-D.
Where is Astronomy Today on our blog and Dictionary
I am not sure why it went away or if I did it intentionally, but I put it back.
well, it ain't there, but the oooold movies and books are. I miss stars and words.
Look now down at the very bottom of the sidebar.
ok thanks but need dictionary also
I have encountered this phenomenon in my day job as a physicist mapping other planets in 3D for NASA...it's the same color fatigue phenomenon that leads to a complimentary color afterimage as in the flag illusion.
Interestingly (I hope) I first encountered the same effect as a kid, napping in my parents' car on road trips. Sunlight shining through the eyelid on one side resulted in everything looking blue through that eye once I opened my eyes. Makes me wonder if you could view red-blue anaglyphs without glasses by "preparing" the eyes with bright blue and red light...
