CiM's Gypsy is a dark, dark transparent purple, so dark, in fact, that the rod just looks black. And a bead made with it and nothing else also looks black. (Left-most bead)
But a dot on white reveals it's red-purple berry-juice nature, and the third bead from the left, Gypsy over clear, also shows it's wine-like nature.
Use as dots, in stringer, over clear, whereever you need a deep, intense colour that can stand to be diluted a lot.
