Sorry for the necropost but I am also wondering something similar, can SRD have CG for an FOC?
Hi. Unfortunately not... just silver or AB. I have a saber with SRD as the main LED and an AB flash. The FoC is noticeable and the combo is lovely. A softer color combo that goes well with both silver and black anodized sabers.
I would imagine that a CG flash would overpower the SRD. Not sure what green color would be produced.
