As far as I know you need to convert both images to grayscale, and *then*
combine the red channel of the left eye's image with the green and blue
channels of the right eye's image.

Yes, you loose all color information in the image, but that's just the way
anaglyph are...

I'm not entirely sure of what I say here, so if anybody knows better, please
tell me.

Probably because the image colors and the colors of the glasses doesn't
match 100%.
I don't know what to do about it, but maybe my above suggestion might help a
little.
