It was made by roasting white lead pigment in the air; the white lead would gradually turn yellow, then into an orange lead tetroxide. The color varied depending upon how long the mineral was roasted. During the Roman Empire, the term minium could refer either to the pigment made from ground cinnabar or to the less expensive red lead. The name came from the river Minius in Iberia (now forming
Cockatiel colour genetics essentially gone. It is only covered up by more grey pigment. There are a tremendous number of colour varieties (combined mutations), including ADMpied Cinnamon, genuine albino, Opaline Cinnamon, Creamino, White-faced Cinnamon, White-faced Opaline. The genuine albino cockatiel is the exact genetic equivalent of any other albino mutation in other parrot species such as the budgerigar, the celestial a.k.a. Pacific parrotlet, the Indian-ringnecked subspecies of rose-ringed parakeet, the splendid a.k.a. scarlet-chested parrot and the white-eye-ringed lovebird species. Throughout all parrot and parakeet species, the genuine albino mutation is always produced by the visual combination of the genuine blue mutation, otherwise known
