This one appeared on e-bay, and it has to be the wildest color insulator I've ever seen, two tone cobalt and violet Neman (HEMAH) C3H (SZN)

I've seen these in cobalt and cornflower, but never in this psych-o-delic "tie dye" color combination.

Neman is still a currently producing glass plant, so there is always the possibility that they could be manufacturing new and "exotic" insulators to meet the collector's desires. No major thing to do like Hemingray did, and run off a few insulators with leftover glass from colorful bottle or "art glass" runs. Maybe some dep-green, ruby red and bright yellow goodies could be on the horizon ? Just a wild speculative guess, but it would be interesting, to say the very least...
