iridescent dye

[TexasStick81]

I'm trying to dye some of my own feathers to match a wrap I'm going to have made based on the iridescents of a peacock feather.  Anybody know where I could find a teal, blue, purple iridescent dye?  I've read of some people using dye for fly fishing and I know iridescent flys are not uncommon.  Any help would be appreciated.

I've seen iridescent paints but never an iridescent dye. I could easily be wrong but I believe the iridescence in paints come from particles in the paint, not sure if that can be done in dyes.
I hope you're able to find some, sounds like a great effect.
