Lutino Gouldian finch

Yellow color in Gouldian Finches is incompletely dominant and sex-linked. ... Lutino is the deficiency of dark pigments in the yellow line, albino is the deficiency of dark pigments in the blue line. Albino is therefore a combination of lutino and blue.

With one of the most striking plumages in the entire animal kingdom, the Gouldian finch almost looks like it was put together in patches. The head, breast, abdomen, and back all exhibit an elegant rainbow of different colors. It's no surprise that this species is highly sought after in the pet trade.

They are small birds, with a bright green back, yellow belly and a purple breast. ... The yellow colour results from a lack of red pigment in the red-faced birds. The males are brighter in plumage than the females. Young Gouldian Finches are dull ashy grey on the head and hind neck, becoming olive on the back and tail.
