As you know, the company most famous for making OEM color CD-Rs is Prodisc.
As you also know, the Khypermedia brand is most known for it's association with lower quality CMC manufactured CD-Rs.
So the question is, what are these? CMC or Prodisc? Something else? Plasmon?
I suppose these could be CMC, since Memorex has the "Cool Colors" line of CD-Rs, and those are most likely CMC.
