You mentioned the SE lightsabers, what did they look like? Where those the ones that were incorrectly colored?

The most incorrectly colored one was Luke's saber in the scene in the Falcon. In the 2004 SE it was green.

In the shot you and I posted, it looks like this:

97 SE, TB broadcast:

2011 blu-ray: (I don't have access to the 2004 SE right now)

If you look closely, the angle of the bottom of the blade is wrong in the SE, if you compare to the GOUT and Senator shot.
