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
Labrador Retriever coat colour genetics characterized in mice and other mammals. Initial genetic studies of coat colour in dogs published in the 1950s concluded that there were two main genes involved, one distinguishing blacks from browns, and the other distinguishing blacks from reds and yellows. A 1977 study using crosses within a population of purebred Labradors showed the involvement of two specific genes in production of the three main coat colours of Labradors and described the underlying genetics of these colour varieties. The three recognised colours of Labrador Retrievers result from differences in two genetic loci that affect pigment expression. The first of these affects
