Cinnamon: prevents the total oxydation of brown pigment into black pigment without reduction of the amount of pigment. The eye is red and quickly darkens with age.



Lutino:  inability to produce melanin pigment, skin, nails and beak are pink, eye is red.

Pallid:  less grey/black pigment is produced than in the wild type, giving a paler look with dark eye and normal beak and nails.

Pallidino:   with one gene for pallid and one for ino, the young are partway between pallid and lutino in colour



Platinum: part of the lutino gene family giving an intermediate mutation lighter than the pallid form



Opaline: it alters pigment distribution reducing spread of black pigments and enhancing the psittacin pigments without altering structural colour production. Enhanced wing stripe in both sexes, grey down turns into white.

autosomal recessive mutations:


Blue: inactivates the production of yellow/ red psittacin pigments which are replaced by pure white colour.

Parblue : intermediate colour between green and blue due to partial activation of the gene, leaving some yellow shades.

  turquoise (european blue)

Pied: stops the deposition of melanin pigments within feathers in an irregular pattern, removes red colouration.

Bronze Fallow: changes all black pigment into light brown shades, the eye is  bright red, skin and nails are pale. The general  colour looks lighter, more or less creamish yellow, male are usually darker than females and some strains are lighter than others.

Black eyed yellow: full pied colour giving a deep yellow colour with black eye ( recessive inheritance)


dominant mutations:


Greygreen: prevents all structural colour producing grey when yellow pigment is removed (with blue) ,dominant inheritance,(single and double factor look similar).
