if i stare at a light bulb for 3 seconds and then look away i see a green bulb next to it for a second or two.  i do know somewhat of what you are talking about, when i was little in elem i would close my eyes and puch them in and i would see black and grey colors forming images and going faster and intensifing. anyone ever done that?

Pushing in my eyeballs right now, I can see colours too. []
There was something about this earlier in this thread.

I see what looks like a green light leading all the pinkish lavender lights around the circle.... like the head of a snake! LOL

Quick. Someone come and rescue me. Chem4me is making me think I'm a freak. Surely someone has experienced this colour change phenominum. Anybody??

I woke up this a.m. and saw some "after images" without having looked into any bright lights...(scary!!) I found this forum while searching for info.

John, I too see "complimentary" colors with eyes open v. closed, when seeing after images. Just thought I would send you this link also, it appears to be documented as a normal aspect of seeing after images: newbielink:http://www.informaworld.com/smpp/content~content=a791215234~db=all~order=page [nonactive]
Specifically, "In some persons, after-images of images occur in complementary colours."

Exactly as u tell it

I found this upon searching for people with similar experiences.  In the animated gif that is in this post when i focus on the center all purple color completely dissapears and I just get left with a green ball that bounces around. 

I've had this happen to me ever since i was a kid.  When I look at light and I close my eyes i see an imprint left.  It's usually purple or green and I can slowly see the color fade away.  I want to use the analogy of a puddle of water slowly evaporating.

(the puddle is the color and spots left in my eye)

Also I believe this is related to the issue of me sneezing when I look at light at certain times of day.

If you want to know the details behind how and why you see weird after-image colours, there's a 2005 paper by Paul Churchland called 'Chimerical Colors: Some Phenomenological Predictions from Cognitive Neuroscience', which describes a complete model of human colour vision with enough detail to allow you to predict what colours you'll see under different conditions.

It gets a bit technical in places, but if you're patient, you'll come to a section near the end that shows you how you can see completely new colours that you'll never see normally; these are the chimerical colours of the title, self-luminous colours, and hyperbolic colours.

It's literally an eye-opener, but you'll need a colour-accurate printer to get the best results.

A cool read Dlorde. I'm looking forward to read it,
