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.
Make sure to check the forum rules and regulations topics, read and sign.
Thanks.
