Mutation colors available are pallid, cinnamon, turquoise, aqua, white chested blue and white chested grey, lutino and violet.
Parblue is in actuality a reference to 3 different colors: Aqua, Turquoise, and AquaTurquoise. The difference between these can sometimes be hard to tell as it depends on the development of the color in the chest and abdomen, especially in young birds. Seagreen is another name for Aqua.
Aqua males have an orange chest and yellow abdomen. Turquoise males have a salmon colored chest and cream abdomen with a strong bluish tint to the back.
Some colors come in combinations like Silver, which is a cinnamon parblue, and has as you would expect - a silvery cast and blue points. Creamino, which is a Parblue Ino, and has a uniformed creamy look to the bird. Albinos, a blue fronted ino, completely lack all color and has red eyes. There are many other color combinations with cinnamon or grey as a base that are less common.
You can also get what is called a red fronted bird where the red extends down into the abdomen and even the female has a red chest, and Pieds where the colors are randomly dispensed throughout the bird. Both of these colors are dominant, you only need 1 bird to have the gene to pass it visibly to the offspring.
There are some colors that are sex linked so that only 1 gender can carry that color while visibly being another. NOTE: ONLY males can carry lutino, a hen is either visibly lutino or she is not a lutino.
Some breeders will also offer splits or the mutation color will carry colors besides what is visible. NOTE: A bird is either visibly violet or its not violet, you cannot carry violet.
For detailed information on the genetics and color combinations along with amazing detailed pictures I highly recommend "A Guide to ... Neophema & Neopsephotus Genera and their Mutations" by Dr. Alain Campagne MD. If you plan on breeding mutation colors it is a MUST HAVE.
Genetics and Colors...
This is a double factor violet male. Thanks Nick Johns for sharing! (Picture was photo enhanced by lightening and sharpening image.) As the violet gene enhances any blue area on a scarlet parakeet - you can find the violet factor in normal as well, but it most striking when seen in a White Chested Blue setting.
This gorgeous Ino Red Fronted scarlet is not yet available in the US...his photo was shared with us from Robin Sheer in the Netherlands. Ino is the genetic designation for Lutino. The red front is a modification gene, not a true mutation, allowing the red of the upper chest extend into the lower belly. Thanks Robin!
These are Aqua (seagreen) mutations. There are 2 males in the back and a hen in the foreground. These are our own birds.
This gorgeous scarlet is an Aqua Grey male, courtesy of Scott Stringer. He is produced by combining two mutations Grey and Blue. For more information on double factor mutations see the above book by Dr. Campagne.
Thanks to Wings Down Under, we can show you a (young) turquoise male. The abdomen is a very light cream, almost white, and he will develop a faint salmon color to the breast. These are 1 step away from being White Chested Blues, all the colors are very dilute and there is a lot of blue.
These are Cinnamon hens with (right) and without (left) the red front. The cinnamon mutation gives them a lighter dusky appearance, thus the name "cinnamon"! Thanks, Wings Down Under!
While the Ino Red Front is not yet available, you can find some breeders getting close with birds that have an extended red in the green color. Thanks Wings Down Under!
Ann was nice enough to share with us a picture of her Albino hen and Single Factor Violet White Chested male. (He recently passed away). You can see how the violet enhances the Blue in the White Chested but as it is a single factor (1 donor) it isn't as deep and dark as the above Double factor violet.
This features a Grey White Chested male, also courtesy of Scott Stringer. Notice the Grey White Chested looks just like a Blue White Chested - but Grey.
Here is a picture of a Silver hen from Scott Stringer. Silver is actually the common name for a Cinnamon Blue which dilutes the blue and gives a brownish cast to the rest of the bird.
