Alternate particle effects for Tech Knight pieces

[Taveena]

This is... obviously not something I expect to be particularly easy, but with the Tech Knight staff, reactor w/fx, capacitor w/fx, shield, and mace, the glow is locked to the same color as the surrounding material. In a lot of design cases, I want the glow to be the OTHER color I'm using so that there's more contrast - a green orb held in a black staff, for example. I have no idea how plausible this would be, but I'd love variants of these costumes that made the glow the OTHER color of the costume piece.
