Orange (colour) Orange (colour) Orange is the colour between yellow and red on the spectrum of visible light. Human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In painting and traditional colour theory, it is a secondary colour of pigments, created by mixing yellow and red. It is named after the fruit of the same name. The orange colour of carrots, pumpkins, sweet potatoes, oranges, and many other fruits and vegetables comes from carotenes, a type of photosynthetic pigment. These pigments convert the light energy that the plants absorb from the sun into chemical
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
