Um, Hi! Welcome to the forums!
Might I politely ask that posting in red be something used sparingly? It's a little hard to read on the grey background. ;)
The Stock blades on the FX's can have a bit paler color to them from time to time. Have you tried installing fresh batteries in the hilt?
I would recommend a set of Duracell Ultra Digitals, or Energizer Titaniums in it. Sometimes weak batteries can make the saber appear a different color tha normal.
It could also be how your eyes perceive the red spectrum, everyone is a little different in how their eves pick up certain colors, so it may just be how you perceive red light.
