I have a few metallic pinks (pigments) too, & picked up a metallic hot pink pigment last week so I'd be interested in some tips too!
One thing I have tried that worked well was -- I put the metallic pink all over the lid with Inglot's Duraline (mixing mediium), I put Inglot's Matte Black pigment (dry) lightly on top & it turned into a cool pink & black duotone.
I always keep the rest of my makeup neutral if I wear a crazy eyeshadow, so nude or light pinks or browns including lipstick.
