Pigment reflect slight variations in molecular structure that produce a slightly more greenish or reddish blue. According to a April 2018 report by "Bloomberg Businessweek", the estimated value of the pigment industry globally is $30 billion. The value of titanium dioxide – used to enhance the white brightness of many products – was placed at $13.2 billion per year, while the color Ferrari red is valued at $300 million each year. Selection of a pigment for a particular application is determined by cost, and by the physical properties and attributes of the pigment itself. For example, a pigment that is used
Cockatiel colour genetics Leading to ADMpied cockatiels being notoriously difficult to sex visually but being excellent examples for studies in genetic traits. However, in monomorphic species (i.e. conures, lovebirds, macaws, rosellas, etc.) the anti-di-morphic feature cannot be expressed while piedness still is. Therefore, Pied specimens of these species are called either Recessive Pied and/or Harlequin in budgerigar. Cinnamon and pearl mutations are sex-linked recessive. In Cinnamons, the eumelanin pigment are partially oxidized. Eumelanin granules are stopped at the brown stage of their development to end up in their natural black colour state. The pearl cockatiels' gene does not have any visual effect on
