All the little textural variations of the glow "field" are identical, it is the same glow as it was in SE.
The original glow was allso greenish, but with a lot less saturation and more leaning to cyan.
I believe that they corrected the sabre locally by boosting its saturation and correcting it to a more pure green.
But I am sure that it was not a newly repainted glow, it's the same old glow, but with a new
color.
Anyway, it has nothing to do with scanning or whatever, the cyan-green glow was there from the begining,
it was just not as pure as now.
