At Picard's I was looking for a sample card (based on a vague memory). No implication that "Africa" was involved in my reasoning.

The beads I have were bought here in the US.

The colors you mention seem as likely to be Venetian as anything else. Perhaps the reality would strike me differently than the effect of the names. "Greasy yellow" is a very typical Venetian color. For that matter, it's Chinese too.... However, I have seen several permutations of these beads in real life. The beads, themselves, are pretty cogent and comparable to other Venetian beads, in terms of sizes/graduation, and bead shape/proportion.

In any event, I would not rule-out Bohemia/Czechoslovakia. I wish I could recall where I saw them on a sample card (if indeed I did).
