red eye, blue eye Canon EOS 20 D

quick question. I've a EOS 20D. 90% of everything I'm shooting people wise has red eye and 95% of animal shots have blue eye. I've got the menu set for red eye "on".

input, suggestions? this is happening on auto zones, semi auto with manual and auto focus...help please

I suppose you are shooting with the pop-up flash. In that case it is nearly impossible to take red eye out all together in dark surrondings. The reason being is that the flash is very close to the center of the focal axis.

To get reduce red-eye a camera sets off pre-flashes, but in dark situations the iris of the eye does not respond to this totally.

The best solution is to buy a flash and then bounce it off the cieling or walls.

Edit: I'm trying to find it in the forums, but some have had luck with placing a ping pong ball over the popup flash.

Unless your flash is acting like a strobe light right before the shutter click to close the iris down and reduce the reflection off the back of the retina, the red eye function isn't working.
On-board flashes do this due to the flash being so close to the sensor.
Off-camera flashes pretty much eliminate this, by placing the flash high above the sensor, or to the side if using a flash bracket.

Believe it or not, cutting a slot in a ping-pong ball and placing it over the top of the flash helps a lot to diffuse the light.

Outside with no flash and getting people red-eye & animal green-eye?
It can only be from the reflection on the back of the eye, and if they are looking into the sun, the iris should have been closed naturally. Can you post an example Sonya?

I'm kinda baffled by that too... an example might help. My first thought would be the flash is popping up for fill, but if you say no flash, we gotta try to find another reason.

.

If you don't have a ping-pong ball, then a small piece of ordinary tissue or white paper napkin/paper towel folded over the on-board flash helps, too.

There are only a couple possibilities here on the shots you uploaded.
A) On-board flash.
B) A strong light source pointed at Ursa and ambient light is low, allowing her irises to open up.
C) A reflection off the front of your lens from a strong light source in front of you and ambient light being low, allowing her irises to open up and catch the reflection off the lens.
D) Somebody is having way too much fun with laser tag.
