Check out http://www.dddesign.com/otherana.htm there is a full color 
anaglyph of some giraffes there. It works fairly well, but mostly 
because there is no glaring Red's or Blue's in the image. If there 
were, then it would be to "loud" in one eye. To create it, you simply 
pull both your left and right images into your image processing 
program. Split the RGB parts of the left image. Copy the RED channel 
from that image. Split the RGB parts of the right image. Paste the RED 
part of the left image over the RED part of the right image. If your 
program lets you do it, make it about 50% transparent so that you can 
see both RED images, and move the Left RED one around until it lines up 
with the Right one to give you the right stereo window (the further to 
the left of the right image you put it, the further back in the window 
the image will sit, but do not abuse this, it can look very bad if 
overdone). Now make the left RED image non transparent again and finish 
the paste. Recombine the RGB parts of the right image. Crop off any 
parts of the images that do not overlap (are not in 3D), and you have a 
full color anaglyph. 

If you find the image is "disturbing" to look at once you have gotten 
this far, you can start over with one small change. Bring in your pair. 
Convert each of them to grayscale images. Now, convert them back to RGB 
images. What you end up with is RGB "grayscale images where you can 
take the "RED" from the left, etc...

Best of luck! I look forward to seeing your anaglyphs some day on the 
web. Let us know when they are ready!! =)
