Looking for a mix that'll match

Now, the Slab Bandit is a Sour Grape (has been real good on Palestine)

The tail is Purple Guined Body with Chartreuse Hackle. I'm gonna play with that purple powder and see if I can get it closer to Grape. Any suggestions on a mix to match that Grape color??

The dollar store sells glitter that same color. Mix it with clear powder. would make a good match.
