Not sure what mib you found on eBay but i can't find any colored Sulphides...
I know SP did some coloring of some Sulphides a while back, not sure when or what ones, but i do recall him saying they was green and blue, and he was pretty tickled knowing he did some Repro's that was going to be passed off as real ones going for big bucks, but that's what he likes, knowing he's ripping some one off...
