Go to hatchery, and at the top, there should be a link called Creatu list. It sorts the pets by planet, but when you select one and view all the colors, it shows all that are available. From the first color down the Albino, the white with red eyes one, those are hatchable. However, as it further advances from natural, they are rarer to get and more expensive to buy from other users. Colors beyond Albino (if any) are dye kit colors and can only be gotten by buying dye kits from the black market located in shop list also on the navigation bar. All dye kits go for over a million, the cheapest being about 2 mil, and can only be used once. Not all pets are available in dye kit colors (such as the Drindians) or any colors, like the Murren and Goiba.
