Single factor dark factor lineolated parakeets (called dark greens) have slightly darker plumage that almost reaches hunter-green on the wings. A double factor, called an olive, is pictured second with swamp-green coloration. When combined with turquoise, a parblue cobalt (pictured third) and parblue mauve (pictured fourth) are produced. Cobalts and mauves are much easier to find than regular dark greens and olives due to their more appealing colors.
