All colors can and will smear but red is the most obvious and especially in dark scenes. Although Squishy's knowledge is great, I totally disagree with him, color smearing is unfortunately not a defective set but inherent to these Samsungs. I went out to best buy with USB stick in hand containing material that I know smears bad and tested out every set of every size on the floor. They all smeared, some worst than others.
BUT there are ways to fix this to different levels. One way is to increase your brightness WAY up (at least 50) and making everything ugly gray and it will fix smearing 100%. I for one am not satisfied at all with this solution.
It is tricky but can be done while keeping some pretty good blacks too. First, get some video that you know smears bad and have it play in loop on your set. There is a sony XBR 1080p smearing video out there on the intertubes that is great for this. You do need to increase your brightness (I think I ended up with 46) a bit and also mess around with gamma. A good way to keep your blacks is to not have the backlight above 8 since you will increase bright and gamma.
Now the real trick is with the white balance. While you are watching the video that smears constantly, adjust the first three sliders of white balance (never remember if those are gain or offset...) You will notice that by increasing or decreasing those 3, the redish smear will change color and can also be green, blue and purple. But you will find a point were the first silder has less noticeable smear. If you go too far left or right, the smear will get worst again. Now do the same with the second slider and you can reduce the smear even more. I got to a point with all three adjusted were I could not see any smear at all on the sony video (black circles scrolling on a blue/gray/white background).
This fixes at least 90% of the problem but you might see a tiny bit of it in some cases but mostly impossible to see.
It did work for me and I still have great blacks. Sounds complicated and it is rather tricky but try adjusting those 3 white balance sliders while watching a loop of "smearing" video.

It really works! Thanks and congratulations. One thinks that by increasing brightness, you could only brighten the shadow so much that it is hard to see it anymore. But that is not the case. It actually disappears after a certain point of brightness while the rest of the normal image is still there. I think increasing the brightness increases the working voltages of the liquid crystals so that they can charge and discharge faster. Hence you do not see the shadows anymore.
Before trying it on my set, I tested the Xbr smearing video on a Samsung 55D8000 in a shop. That video is so extreme that I believed I could see the shadows on D8000 as well. To my surprise there were no shadows at all. The sales guy was so nice that we started to test it on the other sets also. D7000 was also free of the shadows but 46D6000 showed the shadows. The sales guy said it is normal because D8000 and D7000 were 240 Hz but D6000 only 120 Hz. This really discouraged me about your brightness solution. But what I could not understand was why nobody mentioned about it as being 120 hz problem through all these pages in this thread.
Anyway next day I had chance to check it on my set. I started to increase the brightness, and unbelievably the shadows suddenly ceased. Then it occured to me that it had something to do with the bias values of the crystals.
Still what I can not understand is if this is a normal case for this series, then why Samsung keeps silent about red shadow problem which has even complaints without answers in its own Samsung USA site?
Next time I will try to decrease the brightness of D8000 in that shop to see if shadows start to appear or not. If they don't then it means that it has also a lot to do with 120/240 Hz as well.
